A 100 Hz AC generator produces a voltage of 100 V. If the current through a 2 Ω resistor is 5 A, what is the power factor in this circuit?
Q1. A 100 Hz AC generator produces a voltage of 100 V. If the current through a 2 Ω resistor is 5 A, what is the power factor in this circuit?
Answer: 0.5
Explanation: The correct answer is 0.5 because cos(θ) is the definition of the power factor. Option B is an incorrect assumption, option C is an overestimation, and option D is the correct formula but not the correct answer.
