At series or parallel resonance, the circuit power factor is ________________?

Correct answer: C. 1

  • A. 0
  • B. 5
  • C. 1
  • D. 8

Explanation

Resonance cancels the net reactance, leaving the circuit impedance effectively resistive. Voltage and current are then in phase, giving a power factor of 1.
