Definition
SI derived unit of electric potential difference; 1 V = 1 W/A.
Reference value
One volt is equal to 1 volt.
History & use
The volt was included in the international MKS electrical unit definitions ratified in the 1940s; later quantum electrical standards improved practical realization.
Modern use
Standard SI unit for electric potential difference and electromotive force.
Did you know?
The SI relation V = W/A ties voltage directly to power per unit current.
