Detailed explanation-1: -The energy transferred E to a circuit component per unit charge q is called the potential difference PD between the two terminals of the component. The unit of potential difference is also the volt. Units: EMF is measured in Volts (V). Charge is measured in Coulombs (C).

Detailed explanation-2: -Potential difference, or voltage, is the amount of energy transferred per unit charge passed. In other words, it is the amount of energy given to the components in a circuit from the electrons passing through the wire. It is measured in volts-one volt is equivalent to one joule per coulomb.

Detailed explanation-3: -The electrical power is multiplied by time, i.e., E = Pt. Some examples of energy transfer are electric motors, bread toasters at homes, electric irons, etc. The energy transfer in the electric circuits equation is E = QV.

Detailed explanation-4: -E = QV, the energy transferred by the quantity of electric charge by a potential difference of V volts.
