Question

calculate the potential difference is 375 joules of energy is used in transferring a charge of 25 Columb​

Answer 1

As the potential difference between the two terminals of the battery is equal to the work done in moving a unit charge from one terminal to the other. Potential difference V = Total Work done (W) / Total charge (C) ... Potential difference V = W/Q = 100 J/20 C = 5 V.
