  1. Question 1

    Q1. The resonant frequency of an LCR circuit is given by f = 1 / (2π√LC). If L = 1 mH and C = 1 μF, what is the resonant frequency?

    • A) 1591.5 Hz
    • B) 1000 Hz
    • C) 500 Hz
    • D) 2000 Hz

    Answer: 1591.5 Hz

    Explanation: f = 1 / (2π√(1 * 10^(-3) * 1 * 10^(-6))) = 1 / (2 * 3.14 * √(10^(-9))) = 1591.5 Hz.
