For other uses, see Volt (disambiguation). The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
The Electric field can also be noted in units of volts per meter (V/m). A convenient unit of electric potential energy is the electron volt (eV). One electron volt is the potential energy change of moving one electron's worth of charge, e, through one volt. One electron volt equals 1.602E-19 (J).
