Wys bron van Volt

'''Volt''' (simbool: V) is die [[SI-stelsel|SI-eenheid]] waarmee [[Elektriese potensiaal|elektriese stroompotensiaal]] gemeet word. Die eenheid is vernoem na die Italiaanse fisikus, [[Alessandro Volta]] (1745-1827). Hy het die eerste elektriese sel in 1800 ontwikkel. In 1881 is die volt deur die [[International Electrial Congress]] as 'n amptelike eenheid aangeneem.<ref>{{cite book

== Definisie ==
Een volt word gedefinieer as die verskil in elektriese potensiaal tussen twee punte in 'n geleier wanneer 'n elektriese stroom van een ampère een watt [[drywing]] genereer. Of Volt = [[Joule]]/[[Coulomb]]. Dus is:

:<math> \mathrm{V} =  \frac{\mathrm{Q}}{\mathrm{I}}</math>

Waar:
: V = elektriese potensiaal in Volt (V), Q = drywing in watt (W) en I = elektriese stroom in ampère (A)
