56-414: The Indian locomotive class WAG-5 is a class of 25 kV AC electric locomotives that was developed in 1978 by Chittaranjan Locomotive Works for Indian Railways . The model name stands for broad gauge ( W ), alternating current ( A ), goods traffic ( G ) engine, 5th generation ( 5 ). They entered service in 1980. A total of 1196 WAG-5 were built at CLW and BHEL between 1978 and 1998, which made them

112-427: A battery is determined by the chemistry of that cell (see Galvanic cell § Cell voltage ). Cells can be combined in series for multiples of that voltage, or additional circuitry added to adjust the voltage to a different level. Mechanical generators can usually be constructed to any voltage in a range of feasibility. Nominal voltages of familiar sources: In 1800, as the result of a professional disagreement over

168-536: A common typographic practice among both British and U.S. publishers to capitalise significant words (and in the United States, this is often applied to headings, too). This family of typographic conventions is usually called title case . For example, R. M. Ritter's Oxford Manual of Style (2002) suggests capitalising "the first word and all nouns, pronouns, adjectives, verbs and adverbs, but generally not articles, conjunctions and short prepositions". This

224-444: A handwritten sticky note , may not bother to follow the conventions concerning capitalisation, but that is because its users usually do not expect it to be formal. Similar orthographic and graphostylistic conventions are used for emphasis or following language-specific or other rules, including: In English, a variety of case styles are used in various circumstances: In English-language publications, various conventions are used for

280-462: A marker to indicate the beginning of a line of verse independent of any grammatical feature. In political writing, parody and satire, the unexpected emphasis afforded by otherwise ill-advised capitalisation is often used to great stylistic effect, such as in the case of George Orwell's Big Brother . Other languages vary in their use of capitals. For example, in German all nouns are capitalised (this

336-498: A more general sense. It can also be seen as customary to capitalise any word – in some contexts even a pronoun  – referring to the deity of a monotheistic religion . Other words normally start with a lower-case letter. There are, however, situations where further capitalisation may be used to give added emphasis, for example in headings and publication titles (see below). In some traditional forms of poetry, capitalisation has conventionally been used as

392-441: A ratio because the cgs unit of voltage is inconveniently small and one volt in this definition is approximately the emf of a Daniell cell , the standard source of voltage in the telegraph systems of the day. At that time, the volt was defined as the potential difference [i.e., what is nowadays called the "voltage (difference)"] across a conductor when a current of one ampere dissipates one watt of power. The "international volt"

448-533: A series-connected array of several thousand or tens of thousands of junctions , excited by microwave signals between 10 and 80 GHz (depending on the array design). Empirically, several experiments have shown that the method is independent of device design, material, measurement setup, etc., and no correction terms are required in a practical implementation. In the water-flow analogy , sometimes used to explain electric circuits by comparing them with water-filled pipes, voltage (difference in electric potential)

504-555: A shell of the WAM-4. Units numbered till 23293 have side louvre and round glass windows like the WAM-4 and units after 23293 have WAG-7 style of Louvre for better ventilation. Recently, WAG-5 have been fitted with data loggers. Unit numbered 23026 was selected by RDSO for adoption of thyristor controlled electricals in 1995. This was done due to the loss of suppliers of tap changer control. Project began in 1992. The new prototype system built in collaboration with Bhabha Atomic Research Centre

560-478: A spelling mistake (since minuscule is derived from the word minus ), but is now so common that some dictionaries tend to accept it as a non-standard or variant spelling. Miniscule is still less likely, however, to be used in reference to lower-case letters. The glyphs of lowercase letters can resemble smaller forms of the uppercase glyphs restricted to the baseband (e.g. "C/c" and "S/s", cf. small caps ) or can look hardly related (e.g. "D/d" and "G/g"). Here

616-474: Is WAG-5HG. The units with additional '6P' markings have all parallel grouped traction motors. WAG-5HB is built by BHEL. Some units are fitted with Static Converter (STC), Microprocessor, Dynamic brake resistors (DBR) and SI unit. Due to the advent of WAG-7 and WAG-9, these locos except WAG-5HA/HB are even used for passenger trains although it is a freight-dedicated locomotive. WAG-5HB is homed at Jhansi shed near BHEL's installations for maintenance purposes. WAG-5 has

672-508: Is a comparison of the upper and lower case variants of each letter included in the English alphabet (the exact representation will vary according to the typeface and font used): (Some lowercase letters have variations e.g. a/ɑ.) Typographically , the basic difference between the majuscules and minuscules is not that the majuscules are big and minuscules small, but that the majuscules generally are of uniform height (although, depending on

728-414: Is also equivalent to electronvolts per elementary charge : The volt is named after Alessandro Volta . As with every SI unit named for a person, its symbol starts with an upper case letter (V), but when written in full, it follows the rules for capitalisation of a common noun ; i.e., volt becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case. Historically

784-547: Is also known as spinal case , param case , Lisp case in reference to the Lisp programming language , or dash case (or illustratively as kebab-case , looking similar to the skewer that sticks through a kebab ). If every word is capitalised, the style is known as train case ( TRAIN-CASE ). In CSS , all property names and most keyword values are primarily formatted in kebab case. "tHeqUicKBrOWnFoXJUmpsoVeRThElAzydOG" Mixed case with no semantic or syntactic significance to

840-409: Is an old form of emphasis , similar to the more modern practice of using a larger or boldface font for titles. The rules which prescribe which words to capitalise are not based on any grammatically inherent correct–incorrect distinction and are not universally standardised; they differ between style guides, although most style guides tend to follow a few strong conventions, as follows: Title case

896-472: Is capitalised, as are all proper nouns . Capitalisation in English, in terms of the general orthographic rules independent of context (e.g. title vs. heading vs. text), is universally standardised for formal writing. Capital letters are used as the first letter of a sentence, a proper noun, or a proper adjective . The names of the days of the week and the names of the months are also capitalised, as are

952-424: Is capitalised. Nevertheless, the name of the unit, if spelled out, is always considered a common noun and written accordingly in lower case. For example: For the purpose of clarity, the symbol for litre can optionally be written in upper case even though the name is not derived from a proper noun. For example, "one litre" may be written as: The letter case of a prefix symbol is determined independently of

1008-399: Is conventional to use one case only. For example, engineering design drawings are typically labelled entirely in uppercase letters, which are easier to distinguish individually than the lowercase when space restrictions require very small lettering. In mathematics , on the other hand, uppercase and lower case letters denote generally different mathematical objects , which may be related when

1064-501: Is generally applied in a mixed-case fashion, with both upper and lowercase letters appearing in a given piece of text for legibility. The choice of case is often denoted by the grammar of a language or by the conventions of a particular discipline. In orthography , the uppercase is reserved for special purposes, such as the first letter of a sentence or of a proper noun (called capitalisation, or capitalised words), which makes lowercase more common in regular text. In some contexts, it

1120-606: Is likened to difference in water pressure , while current is proportional to the amount of water flowing. A resistor would be a reduced diameter somewhere in the piping or something akin to a radiator offering resistance to flow. The relationship between voltage and current is defined (in ohmic devices like resistors ) by Ohm's law . Ohm's Law is analogous to the Hagen–Poiseuille equation , as both are linear models relating flux and potential in their respective systems. The voltage produced by each electrochemical cell in

1176-422: Is no technical requirement to do so – e.g., Sun Microsystems ' naming of a windowing system NeWS . Illustrative naming of the style is, naturally, random: stUdlY cAps , StUdLy CaPs , etc.. In the character sets developed for computing , each upper- and lower-case letter is encoded as a separate character. In order to enable case folding and case conversion, the software needs to link together

1232-405: Is not available. Acronyms (and particularly initialisms) are often written in all-caps , depending on various factors . Capitalisation is the writing of a word with its first letter in uppercase and the remaining letters in lowercase. Capitalisation rules vary by language and are often quite complex, but in most modern languages that have capitalisation, the first word of every sentence

1288-853: Is removed and spaces are replaced by single underscores . Normally the letters share the same case (e.g. "UPPER_CASE_EMBEDDED_UNDERSCORE" or "lower_case_embedded_underscore") but the case can be mixed, as in OCaml variant constructors (e.g. "Upper_then_lowercase"). The style may also be called pothole case , especially in Python programming, in which this convention is often used for naming variables. Illustratively, it may be rendered snake_case , pothole_case , etc.. When all-upper-case, it may be referred to as screaming snake case (or SCREAMING_SNAKE_CASE ) or hazard case . "the-quick-brown-fox-jumps-over-the-lazy-dog" Similar to snake case, above, except hyphens rather than underscores are used to replace spaces. It

1344-572: Is sentence-style capitalisation in headlines, i.e. capitalisation follows the same rules that apply for sentences. This convention is usually called sentence case . It may also be applied to publication titles, especially in bibliographic references and library catalogues. An example of a global publisher whose English-language house style prescribes sentence-case titles and headings is the International Organization for Standardization (ISO). For publication titles it is, however,

1400-578: Is the elementary charge and h is the Planck constant ), a "conventional" value K J-90 = 0.4835979 GHz/μV was used for the purpose of defining the volt. As a consequence of the 2019 revision of the SI , as of 2019 the Josephson constant has an exact value of K J = 483 597 .848 416 98 ... GHz/V , which replaced the conventional value K J-90 . This standard is typically realized using

1456-418: Is the distinction between the letters that are in larger uppercase or capitals (more formally majuscule ) and smaller lowercase (more formally minuscule ) in the written representation of certain languages. The writing systems that distinguish between the upper- and lowercase have two parallel sets of letters: each in the majuscule set has a counterpart in the minuscule set. Some counterpart letters have

1512-435: Is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m , kg , s , and A ) as It can also be expressed as amperes times ohms (current times resistance, Ohm's law ), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which

1568-424: Is widely used in many English-language publications, especially in the United States. However, its conventions are sometimes not followed strictly – especially in informal writing. In creative typography, such as music record covers and other artistic material, all styles are commonly encountered, including all-lowercase letters and special case styles, such as studly caps (see below). For example, in

1624-520: The wordmarks of video games it is not uncommon to use stylised upper-case letters at the beginning and end of a title, with the intermediate letters in small caps or lower case (e.g., ArcaniA , ArmA , and DmC ). Single-word proper nouns are capitalised in formal written English, unless the name is intentionally stylised to break this rule (such as e e cummings , bell hooks , eden ahbez , and danah boyd ). Multi-word proper nouns include names of organisations, publications, and people. Often

1680-496: The " conventional " volt, V 90 , defined in 1987 by the 18th General Conference on Weights and Measures and in use from 1990 to 2019, was implemented using the Josephson effect for exact frequency-to-voltage conversion, combined with the caesium frequency standard . Though the Josephson effect is still used to realize a volt, the constant used has changed slightly. For the Josephson constant , K J = 2 e / h (where e

1736-722: The British Association for the Advancement of Science had defined the volt, ohm, and farad. In 1881, the International Electrical Congress, now the International Electrotechnical Commission (IEC), approved the volt as the unit for electromotive force. They made the volt equal to 10 cgs units of voltage, the cgs system at the time being the customary system of units in science. They chose such

1792-562: The WAG-5 locomotives were relegated to hauling smaller passenger trains and now the aging fleet the WAG-5 locomotives are rapidly being withdrawn from mainline duties and scrapped. WAG-5A is the one with Alstom traction motors. WAG-5B is a converted WAM-4 . WAG-5H(x) is with Hitachi traction motors. WAG-5P(x) is a passenger dedicated class. WAG-5(x)D are fitted with dual brakes and WAG-5(x)E are fitted with air brakes. WAG-5RH and WAG-5HR are fitted with Rheostatic or Friction braking. Another variant

1848-581: The capitalisation of the following internal letter or word, for example "Mac" in Celtic names and "Al" in Arabic names. In the International System of Units (SI), a letter usually has different meanings in upper and lower case when used as a unit symbol. Generally, unit symbols are written in lower case, but if the name of the unit is derived from a proper noun, the first letter of the symbol

1904-414: The capitalisation of words in publication titles and headlines , including chapter and section headings. The rules differ substantially between individual house styles. The convention followed by many British publishers (including scientific publishers like Nature and New Scientist , magazines like The Economist , and newspapers like The Guardian and The Times ) and many U.S. newspapers

1960-446: The case is usually known as lower camel case or dromedary case (illustratively: dromedaryCase ). This format has become popular in the branding of information technology products and services, with an initial "i" meaning " Internet " or "intelligent", as in iPod , or an initial "e" meaning "electronic", as in email (electronic mail) or e-commerce (electronic commerce). "the_quick_brown_fox_jumps_over_the_lazy_dog" Punctuation

2016-418: The code too abstract and overloaded for the common programmer to understand. Understandably then, such coding conventions are highly subjective , and can lead to rather opinionated debate, such as in the case of editor wars , or those about indent style . Capitalisation is no exception. "theQuickBrownFoxJumpsOverTheLazyDog" or "TheQuickBrownFoxJumpsOverTheLazyDog" Spaces and punctuation are removed and

2072-404: The context of an imperative, strongly typed language. The third supports the macro facilities of LISP, and its tendency to view programs and data minimalistically, and as interchangeable. The fourth idiom needs much less syntactic sugar overall, because much of the semantics are implied, but because of its brevity and so lack of the need for capitalization or multipart words at all, might also make

2128-464: The first letter of each word is capitalised. If this includes the first letter of the first word (CamelCase, " PowerPoint ", "TheQuick...", etc.), the case is sometimes called upper camel case (or, illustratively, CamelCase ), Pascal case in reference to the Pascal programming language or bumpy case . When the first letter of the first word is lowercase (" iPod ", " eBay ", "theQuickBrownFox..."),

2184-437: The first-person pronoun "I" and the vocative particle " O ". There are a few pairs of words of different meanings whose only difference is capitalisation of the first letter. Honorifics and personal titles showing rank or prestige are capitalised when used together with the name of the person (for example, "Mr. Smith", "Bishop Gorman", "Professor Moore") or as a direct address, but normally not when used alone and in

2240-415: The galvanic response advocated by Luigi Galvani , Alessandro Volta developed the so-called voltaic pile , a forerunner of the battery , which produced a steady electric current . Volta had determined that the most effective pair of dissimilar metals to produce electricity was zinc and silver . In 1861, Latimer Clark and Sir Charles Bright coined the name "volt" for the unit of resistance. By 1873,

2296-578: The majuscule scripts used in the Codex Vaticanus Graecus 1209 , or the Book of Kells ). By virtue of their visual impact, this made the term majuscule an apt descriptor for what much later came to be more commonly referred to as uppercase letters. Minuscule refers to lower-case letters . The word is often spelled miniscule , by association with the unrelated word miniature and the prefix mini- . That has traditionally been regarded as

2352-433: The modern written Georgian language does not distinguish case. All other writing systems make no distinction between majuscules and minuscules – a system called unicameral script or unicase . This includes most syllabic and other non-alphabetic scripts. In scripts with a case distinction, lowercase is generally used for the majority of text; capitals are used for capitalisation and emphasis when bold

2408-536: The most numerous class of mainline electric locomotive until the introduction of its successor, the WAG-7. The WAG-5 is one of the most successful locomotives of Indian Railways currently serving both freight and passenger trains for over 43 years. This class provided the basic design for a number of other locomotives, like WAG-7 and the WCM-6 . However, with the advent of new 3-phase locomotives like WAG-9 and WAG-12 ,

2464-753: The name, though there is some variation in this. With personal names , this practice can vary (sometimes all words are capitalised, regardless of length or function), but is not limited to English names. Examples include the English names Tamar of Georgia and Catherine the Great , " van " and "der" in Dutch names , " von " and "zu" in German , "de", "los", and "y" in Spanish names , "de" or "d'" in French names , and "ibn" in Arabic names . Some surname prefixes also affect

2520-718: The ones with descenders. In addition, with old-style numerals still used by some traditional or classical fonts, 6 and 8 make up the ascender set, and 3, 4, 5, 7 , and 9 the descender set. A minority of writing systems use two separate cases. Such writing systems are called bicameral scripts . These scripts include the Latin , Cyrillic , Greek , Coptic , Armenian , Glagolitic , Adlam , Warang Citi , Garay , Zaghawa , Osage , Vithkuqi , and Deseret scripts. Languages written in these scripts use letter cases as an aid to clarity. The Georgian alphabet has several variants, and there were attempts to use them as different cases, but

2576-475: The rules for "title case" (described in the previous section) are applied to these names, so that non-initial articles, conjunctions, and short prepositions are lowercase, and all other words are uppercase. For example, the short preposition "of" and the article "the" are lowercase in "Steering Committee of the Finance Department". Usually only capitalised words are used to form an acronym variant of

2632-402: The same shape, and differ only in size (e.g. ⟨C, c⟩ or ⟨S, s⟩ ), but for others the shapes are different (e.g., ⟨A, a⟩ or ⟨G, g⟩ ). The two case variants are alternative representations of the same letter: they have the same name and pronunciation and are typically treated identically when sorting in alphabetical order . Letter case

2688-511: The shallow drawers called type cases used to hold the movable type for letterpress printing . Traditionally, the capital letters were stored in a separate shallow tray or "case" that was located above the case that held the small letters. Majuscule ( / ˈ m æ dʒ ə s k juː l / , less commonly / m ə ˈ dʒ ʌ s k juː l / ), for palaeographers , is technically any script whose letters have very few or very short ascenders and descenders, or none at all (for example,

2744-561: The tokens, such as function and variable names start to multiply in complex software development , and there is still a need to keep the source code human-readable, Naming conventions make this possible. So for example, a function dealing with matrix multiplication might formally be called: In each case, the capitalisation or lack thereof supports a different function. In the first, FORTRAN compatibility requires case-insensitive naming and short function names. The second supports easily discernible function and argument names and types, within

2800-405: The two cases of the same letter are used; for example, x may denote an element of a set X . The terms upper case and lower case may be written as two consecutive words, connected with a hyphen ( upper-case and lower-case  – particularly if they pre-modify another noun), or as a single word ( uppercase and lowercase ). These terms originated from the common layouts of

2856-425: The typeface, there may be some exceptions, particularly with Q and sometimes J having a descending element; also, various diacritics can add to the normal height of a letter). There is more variation in the height of the minuscules, as some of them have parts higher ( ascenders ) or lower ( descenders ) than the typical size. Normally, b, d, f, h, k, l, t are the letters with ascenders, and g, j, p, q, y are

2912-596: The unit symbol to which it is attached. Lower case is used for all submultiple prefix symbols and the small multiple prefix symbols up to "k" (for kilo , meaning 10 = 1000 multiplier), whereas upper case is used for larger multipliers: Some case styles are not used in standard English, but are common in computer programming , product branding , or other specialised fields. The usage derives from how programming languages are parsed , programmatically. They generally separate their syntactic tokens by simple whitespace , including space characters , tabs , and newlines . When

2968-445: The use of the capitals. Sometimes only vowels are upper case, at other times upper and lower case are alternated, but often it is simply random. The name comes from the sarcastic or ironic implication that it was used in an attempt by the writer to convey their own coolness ( studliness ). It is also used to mock the violation of standard English case conventions by marketers in the naming of computer software packages, even when there

3024-416: Was defined in 1893 as 1 ⁄ 1.434 of the emf of a Clark cell . This definition was abandoned in 1908 in favor of a definition based on the international ohm and international ampere until the entire set of "reproducible units" was abandoned in 1948. A 2019 revision of the SI , including defining the value of the elementary charge , took effect on 20 May 2019. Upper case Letter case

3080-528: Was fitted in the locomotive between 1997 and 1998. However, due to several problems like interference with signalling equipment, the project was ceased in 1999. The engine was rebuilt to original WAG-5 and designated as WAG-5P. Volt One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. It can be expressed in terms of SI base units ( m , kg , s , and A ) as Equivalently, it

3136-635: Was previously common in English as well, mainly in the 17th and 18th centuries), while in Romance and most other European languages the names of the days of the week, the names of the months, and adjectives of nationality, religion, and so on normally begin with a lower-case letter. On the other hand, in some languages it is customary to capitalise formal polite pronouns , for example De , Dem ( Danish ), Sie , Ihnen (German), and Vd or Ud (short for usted in Spanish ). Informal communication, such as texting , instant messaging or
