For a parallel RLC circuit at ideal resonance, the input susceptance is?

  • AMaximum positive
  • BMaximum negative
  • CZero
  • DEqual to resistance
Report an error
Correct Answer: C. Zero
Explanation: At parallel resonance, inductive and capacitive susceptances cancel, leaving zero net susceptance.
Reference: Standard network theory: parallel resonance
