Volt :
The volt (V) is the derived SI unit of electric potential or electromotive force that causes the electrons to move. Since a source of electricity creates energy, a volt can be defined as the potential difference between two points in an electric circuit that will impart one joule (J) of energy per coulomb (C) of charge that passes through it.
V = J/C
Voltage can also be stated as electric potential along a wire when an electric current of one ampere dissipates one watt (W) of power (W = J/s).
V = W/A
A volt can be stated in SI base units as 1 V = 1 kg m2 s−3 A−1 (one kilogram meter squared per second cubed per ampere).
Considering the official SI definition of an ampere, a volt is also equal to the potential difference between two parallel, infinite planes spaced 1 meter apart that create an electric field of 1 newton per coulomb.
