Resonance — Q Factor MeaningMediumQuestion 20223

Question

A series LCR circuit has Q = 100. At resonance, if supply voltage is 5 V, voltage across inductor is:
  1. A
    5 V
  2. B
    100 V
  3. C
    500 V
    Correct
  4. D
    0.05 V

Correct answer

500 V

Explanation

V_L = Q × V_supply = 100 × 5 = 500 V at resonance. This voltage magnification can be destructive if not accounted for in circuit design.
