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