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

Question

Philoid · Accepted Answer

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.
