Question

The work done in moving a charge of 2 coulomb (C) from point A to point B is 24 J. What is the potential difference between A and B?

The correct answer is

12 V

Correct Answer: (c) 12 V

Explanation: Potential difference (V) is given by the formula V = Work Done / Charge. Here, V = 24 J / 2 C = 12 V.
