Final answer:
The energy carried by each unit of moving charge in a circuit is called electric potential energy. The formula for electric potential energy is PE = qV, where q is the charge moved and V is the voltage or potential difference through which the charge moves.
Step-by-step explanation:
The energy carried by each unit of moving charge in a circuit is called electric potential energy. It is the work that a charge can do by virtue of its position in an electric field. The formula for electric potential energy is PE = qV, where q is the charge moved and V is the voltage or potential difference through which the charge moves.
