NEET Physics Power in AC Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
In an AC circuit, the rms voltage is 220 V and the resistance is 50 Ω. What is the average power consumed in the circuit?
A
968 W
B
484 W
C
220 W
D
110 W
Correct Answer
Option B
Detailed Explanation
The average power in an AC circuit is given by P = V²/R where V is the rms voltage. Thus, P = (220)²/50 = 484 W.
