  1. Question 1

    Q1. The average power consumed in an AC circuit is given by

    • A) V_rms * I_rms
    • B) V_rms * I_rms * cos(φ)
    • C) V₀ * I₀
    • D) V₀ * I₀ * cos(φ)

    Answer: V_rms * I_rms * cos(φ)

    Explanation: Average power = V_rms * I_rms * cos(φ), where cos(φ) is the power factor. Option A is incorrect as it lacks the power factor.
