  1. Question 1

    Q1. In an AC circuit, the voltage across the resistor is in phase with the current. What is the power factor in this circuit?

    • A) 0.5
    • B) 0.7
    • C) 0.9
    • D) cos(θ)

    Answer: cos(θ)

    Explanation: The correct answer is cos(θ) because it represents the real power component. Option A is an incorrect assumption, option B is an overestimation, and option C is the power factor angle.
