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

The potential difference (V) between two points is defined as the work done (W) per unit charge (Q) in moving the charge between those points. The formula is V = W/Q. Given W = 24 J and Q = 2 C, the potential difference V = 24 J / 2 C = 12 V. Therefore, the potential difference between points A and B is 12 volts. This is a direct application of the definition of electric potential difference, which is measured in volts (1 V = 1 J/C).
