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?

Options

  1. A48 V
  2. B6 V
  3. C12 V
  4. D0.08 V

Correct answer

C. 12 V

Step-by-step solution

Given W=24W = 24 J and Q=2Q = 2 C.

The potential difference ΔV\Delta V between points A and B is given by the formula:

ΔV=WQ\Delta V = \dfrac{W}{Q}

Substituting the given values:

ΔV=242=12\Delta V = \dfrac{24}{2} = 12 V.

Answer: 12 V
