An AC source is connected to a 10 Ω resistor. If rms current is 2 A, find average power dissipated.
Q1. An AC source is connected to a 10 Ω resistor. If rms current is 2 A, find average power dissipated.
Answer: 40 W
Explanation: Use P = I²rms * R, where Irms = 2 A and R = 10 Ω. So, P = (2)² * 10 = 40 W.
