  1. Question 1

    Q1. An AC generator produces an emf given by ε = 200 sin(100πt). What is the frequency of the generator?

    • A) 50 Hz
    • B) 100 Hz
    • C) 25 Hz
    • D) 200 Hz

    Answer: 50 Hz

    Explanation: ε = ε₀ sin(2πft); 2πf = 100π, so f = 50 Hz. Option B is incorrect due to wrong identification of the coefficient of t.
