  1. Question 1

    Q1. A 50 Hz AC source is connected to a circuit. The time taken by the current to reach its peak value from zero 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 from zero is T / 4 = 1 / 200 s.
