MCQ Practice Question

At parallel resonance in an ideal parallel RLC circuit, the input impedance is ideally?

  • AMinimum and zero
  • BMaximum
  • CEqual to inductive reactance only
  • DAlways 1 ohm
Report an error
Correct Answer: B. Maximum
Explanation: At parallel resonance the reactive branch currents cancel at the input, making the input admittance minimum and impedance maximum in the ideal case.
