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 for AC quantities are not commonly used in calculations.
The power factor can never exceed 1 in any AC circuit.
Instantaneous power in an AC circuit is always positive.
Correct Answer
Detailed Explanation
The average power supplied to an inductor over one complete cycle is indeed zero, as the average of the sine function over a complete cycle is zero, indicating no net energy transfer. This is highlighted in the NCERT context provided.
