Levolt(symbolo:V) es leunitate derivatedefortia electromotivein leSystema International de Unitates,communmente appellate "voltage". Illo es anque le unitate pro le connexe ma legiermente differente quantitatepotential electricin un puncto (voltage como connexe a unterra referential) edifferentia potential electric(anque appellate "differentia potential electrostatic" ). Illo es nominate pro del physico italianoAlessandro Volta(1745–1827), qui inventava lepila voltaic,forsan le primepilachimic.

Definition

Le volt es definite como le valor delvoltagetrans unconductorquando uncurrentede unamperedissipa unwattdepotentiain le conductor.

Illo etiam equala unjouledeenergiapercoulombdecarga electric,J/C. Illo pote esser exprimite in terminos del unitates del SI como:

${\mbox{V}}={\mbox{A}}\cdot \Omega ={\dfrac {\mbox{W}}{\mbox{A}}}={\sqrt {{\mbox{W}}\cdot \Omega }}={\dfrac {\mbox{J}}{{\mbox{A}}\cdot {\mbox{s}}}}={\dfrac {{\mbox{N}}\cdot {\mbox{m}}}{{\mbox{A}}\cdot {\mbox{s}}}}={\dfrac {{\mbox{kg}}\cdot {\mbox{m}}^{2}}{{\mbox{C}}\cdot {\mbox{s}}^{2}}}={\dfrac {{\mbox{N}}\cdot {\mbox{m}}}{\mbox{C}}}={\dfrac {\mbox{J}}{\mbox{C}}}$

Illo anque pote esser scribite in leunitates de base del SIm,kg,seAcomo:

${\mbox{V}}={\dfrac {{\mbox{kg}}\cdot {\mbox{m}}^{2}}{{\mbox{A}}\cdot {\mbox{s}}^{3}}}$
