NEET Physics Power in AC Circuits MCQ Question
Consider a phasor diagram where a resistor of 100 Ω is connected to an AC source of 220 V, 50 Hz. Which of the following represents the correct calculation for the net power consumed over a complete cycle in this circuit?
P = V_rms^2 / R
P = V_peak^2 / R
P = I_rms^2 * R
P = I_peak^2 * R
Correct Answer
Detailed Explanation
The net power consumed over a complete cycle in an AC circuit is given by the formula P = V_rms^2 / R, which uses the root mean square (rms) values. This is derived from the average power formula for AC circuits in the NCERT context.
