Electrical Potential
Electrical potential is the potential energy per unit charge associated with a static (time-invariant) electric field, also called the electrostatic potential or the electric potential, typically measured in volts. Technically, it is the potential ? (a scalar field) associated with the conservative electric field E (E = ???) that occurs when the magnetic field is time invariant (so that ? × E = 0 from Faraday's law of induction).
The electrical potential is measured in units of energy per unit of electric charge. In SI units, this is:
joules/coulombs = volts.
