  1. Question 1

    Q1. In an AC circuit, the rms value of current is 5 A. What is the peak value of current?

    • A) 7.07 A
    • B) 3.53 A
    • C) 10 A
    • D) 2.5 A

    Answer: 7.07 A

    Explanation: I_rms = I₀/√2; I₀ = I_rms * √2 = 5 * 1.414 = 7.07 A. Option B is incorrect due to wrong calculation.
