Volt

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:

${\displaystyle \mathrm {V} ={\frac {\mathrm {Q} }{\mathrm {I} }}}$

Waar:

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