  1. Question 1

    Q1. A series RLC circuit is at resonance. What is the impedance?

    • A) R
    • B) Xl
    • C) Xc
    • D) sqrt(R^2 + Xl^2)

    Answer: R

    Explanation: At resonance, Xl = Xc, so the impedance Z = R. Option B is incorrect because it is the inductive reactance, not the impedance at resonance.
