NEET Physics Power in AC Circuits MCQ Question
Type: MCQ-numerical-Easy-Class 12
A 220 V AC supply is connected to a 100 Ω resistor. What is the net power consumed by the resistor over a full cycle?
A
440 W
B
484 W
C
220 W
D
110 W
Correct Answer
Option B
Detailed Explanation
The average power consumed in an AC circuit with a resistor is given by P = V^2/R. Using rms voltage, P = (220)^2 / 100 = 484 W.
