Question
A resistor, 100Ω, is connected to an a.c. source v = 300 sin ωt. If ω=1256 rad/s, find the power dissipated.
Correct Answer
Option C is the correct answer.
Detailed Explanation
V_rms = 300/√2 = 212.1V; P = V_rms²/R = 212.1²/100 = 450W
Hint
Power in AC is calculated using the RMS voltage, which is Peak/√2.
