Electrical energy

If a charge Q moves between two points in a circuit that have a potential difference of V volts between them the energy gained (or lost) by the charge is given by the formula:

Electrical energy = Charge x Potential difference(Voltage)
Joules = Coulombs x Volts = Amps x Time x Volts

But since Q = It we have:

Electrical energy = ItV
