NEET Physics Power in AC Circuits MCQ Question
Which of the following statements about power in AC circuits is correct?
The average power consumed in an AC circuit can be zero if the circuit contains only inductors.
RMS values are used to express AC current and voltage for calculating average power.
AC circuits behave differently from DC circuits in terms of power consumption.
The average power in a resistive AC circuit is always greater than the maximum instantaneous power.
Correct Answer
Detailed Explanation
RMS values are essential in AC circuits as they allow for the calculation of average power using the same equations as in DC circuits. Option A is incorrect because while the average power in an inductor is zero, this is not the case for circuits containing resistors. Options C and D are misleading as they don't accurately reflect the principles of power in AC circuits.
