  1. Question 1

    Q1. The rms value of an AC current is 2 A. What is the peak value of the current?

    • A) 1.414 A
    • B) 2.828 A
    • C) 4 A
    • D) 5.657 A

    Answer: 2.828 A

    Explanation: I_peak = I_rms * sqrt(2) = 2 A * sqrt(2) = 2.828 A. Option A is incorrect because it is the rms value divided by sqrt(2).
