An AC source with a frequency of 50 Hz is connected to a series RLC circuit. If L = 0.1 H and C = 100 μF, what is the resonant frequency?
Q1. An AC source with a frequency of 50 Hz is connected to a series RLC circuit. If L = 0.1 H and C = 100 μF, what is the resonant frequency?
Answer: 50 Hz
Explanation: f_res = 1 / (2π sqrt(LC)) = 1 / (2π sqrt(0.1 H * 100e-6 F)) = 50 Hz (approx). Option A is incorrect because it is not the calculated resonant frequency.
