  1. Question 1

    Q1. The rms value of an AC of 50 Hz is 10 A. The time taken by the AC to reach its peak value is

    • A) 1 / 100 s
    • B) 1 / 50 s
    • C) 1 / 200 s
    • D) 1 / 400 s

    Answer: 1 / 200 s

    Explanation: Time period T = 1 / f = 1 / 50 s. Time to reach peak = T / 4 = 1 / 200 s.
