  1. Question 1

    Q1. A series LCR circuit has R = 10 Ω, L = 0.1 H, and C = 100 μF. What is the resonant frequency?

    • A) 50 / π Hz
    • B) 100 / π Hz
    • C) 50 Hz
    • D) 100 Hz

    Answer: 50 / π Hz

    Explanation: The resonant frequency f = 1 / (2π√(LC)), so f = 1 / (2π√(0.1 * 100 * 10^(-6))) = 50 / π Hz.
