  1. Question 1

    Q1. The rms value of current in an AC circuit is 10 A. What is the peak current?

    • A) 14.14 A
    • B) 7.07 A
    • C) 10 A
    • D) 20 A

    Answer: 14.14 A

    Explanation: The rms value is related to peak value by Irms = I0 / √2. So, I0 = Irms * √2 = 10 * √2 = 14.14 A.
