For other uses, see Volt (disambiguation). The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
In high-energy physics, electron-volt is often used as a unit of momentum. A potential difference of 1 volt causes an electron to gain a discrete amount of energy (i.e., 1 eV). This gives rise to usage of eV (and keV, MeV, GeV or TeV) as units of momentum, for the energy supplied results in acceleration of the particle.he list of authors can be seen in the page history.

In physics, the electron volt (symbol eV; also written electronvolt) is a unit of energy equal to approximately 1.602Ã10â19 joule (symbol J).
