LCR — Resonance ConditionEasyQuestion 20243

Question

At resonance in a series LCR circuit, the impedance equals:
  1. A
    Zero
  2. B
    R
    Correct
  3. C
    X_L
  4. D
    X_C

Correct answer

R

Explanation

At resonance X_L = X_C → (X_L − X_C) = 0 → Z = √(R² + 0) = R. The circuit behaves as a pure resistor.
