Q15 of 330 Page 5

How much energy is transferred by a 12 V power supply to each coulomb of charge which it moves around a circuit?

Here potential difference = 12 V

Charge moved = 1 C


Work done = Potential difference × Charge moved


= 12 × 1 = 12 joule


So 12 J energy is transferred by a 12 V power supply to each coulomb of charge which it move around a circuit.
