Arrangiamento de junctiones de Josephson disveloppate per NIST como un volt standard.

Le volt (symbolo: V) es le unitate derivate de fortia electromotive in le Systema International de Unitates, communmente appellate "voltage". [1] Illo es anque le unitate pro le connexe ma legiermente differente quantitate potential electric in un puncto (voltage como connexe a un terra referential) e differentia potential electric (anque appellate "differentia potential electrostatic"). Illo es nominate pro del physico italiano Alessandro Volta (1745–1827), qui inventava le pila voltaic, forsan le prime pila chimic.

Le volt es definite como le valor del voltage trans un conductor quando un currente de un ampere dissipa un watt de potentia in le conductor. [2]

Illo etiam equala un joule de energia per coulomb de carga electric, J/C. Illo pote esser exprimite in terminos del unitates del SI como:

Illo anque pote esser scribite in le unitates de base del SI m, kg, s e A como:
