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.
Definition
[modificar | modificar fonte]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:
