  1. Question 1

    Q1. In an AC circuit, the current lags the voltage by 60°. What is the power factor in this circuit?

    • A) cos(60°)
    • B) sin(60°)
    • C) tan(60°)
    • D) 0.5

    Answer: cos(60°)

    Explanation: The correct answer is cos(60°) because it represents the real power component. Option B is the imaginary power component, option C is the power factor angle, and option D is an incorrect assumption.
