What determines the rate at which energy is delivered by a current?
Correct Answer
Power determines the rate at which energy is delivered by a current. It is given by the relation P = VI, where V is the potential difference across the resistor and I is the current flowing through it.

Explanation
According to the textbook context, the power input to the circuit by the source is expressed as P = VI. This power represents the rate at which energy is supplied by the source. The context states that 'the source must supply energy equal to VQ in time t' and 'the power input to the circuit by the source is P = VI'. Thus, power is the rate of energy delivery, determined by both the potential difference and the current.
