  1. Question 1

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

    • A) R
    • B) X_L
    • C) X_C
    • D) √(R^2 + (X_L - X_C)^2)

    Answer: R

    Explanation: At resonance, X_L = X_C, so impedance equals resistance R. Option D is the general impedance formula, not specific to resonance.
