A 50 Hz AC generator produces a voltage of 220 V. If the current through a 10 Ω resistor is 5 A, what is the power consumed?
Q1. A 50 Hz AC generator produces a voltage of 220 V. If the current through a 10 Ω resistor is 5 A, what is the power consumed?
Answer: 110 W
Explanation: The correct answer is 110 W because P = V * I * cos(θ), and cos(θ) is approximately 1 for a resistive load. Option A assumes θ is 90°, option B assumes θ is 0°, and option C assumes θ is 45°.
