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 electric potential difference (V) between two points is defined as the work done (W) per unit charge (q) in moving that charge from one point to another. Mathematically, this relationship is expressed by the formula V = W / q. In the given problem, the work done (W) is 24 Joules (J) and the magnitude of the charge (q) being moved is 2 Coulombs (C). By substituting these values into the formula, we calculate the potential difference as V = 24 J / 2 C, which equals 12 Volts (V). One Volt is equivalent to one Joule per Coulomb, representing the energy gained or lost by a unit charge moving through that potential difference. Therefore, the potential difference between points A and B is 12 V.
