![]() ![]() The International Electrotechnical Commission began work on terminology in 1909 and established Technical Committee 1 in 1911, its oldest established committee, "to sanction the terms and definitions used in the different electrotechnical fields and to determine the equivalence of the terms used in the different languages." In a February 1902 manuscript, with handwritten notes of Oliver Heaviside, Giovanni Giorgi proposed a set of rational units of electromagnetism including the weber, noting that "the product of the volt into the second has been called the weber by the B. ![]() In 1861, the British Association for the Advancement of Science (known as "The BA" ) established a committee under William Thomson (later Lord Kelvin) to study electrical units. As with every SI unit named for a person, its symbol starts with an upper case letter (Wb), but when written in full it follows the rules for capitalisation of a common noun i.e., " weber" becomes capitalised at the beginning of a sentence and in titles, but is otherwise in lower case. The weber is named after Wilhelm Eduard Weber. Where Ω is ohm, C is coulomb, J is joule, and N is newton. Weber (unit of magnetic flux) - The weber is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second. A change in flux of one weber per second will induce an electromotive force of one volt (produce an electric potential difference of one volt across two open-circuited terminals). The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891). A magnetic flux density of one Wb/m 2 (one weber per square metre) is one tesla. ər/ VAY-, WEH-bər symbol: Wb) is the unit of magnetic flux in the International System of Units (SI), whose units are volt-second. In physics, the weber ( / ˈ v eɪ b-, ˈ w ɛ b. ![]()
