NEET Physics Power in AC Circuits MCQ Question
Which of the following statements about power in AC circuits is correct?
The average power supplied to an inductor over one complete cycle is zero.
RMS values of voltage and current are always equal to their maximum values.
The power factor is defined as the ratio of average power to the product of RMS voltage and RMS current.
Reactance in an AC circuit does not affect the current flow in the circuit.
Correct Answer
Detailed Explanation
The average power supplied to an inductor over one complete cycle is indeed zero, as the average of sin(2ωt) over a complete cycle is zero, indicating that the inductor does not consume power like a resistance.
