In a series L-C circuit at the resonant frequency the__________?

Correct answer: A. current is maximum

  • A. current is maximum
  • B. current is minimum
  • C. impedance is maximum
  • D. voltage across C is minimum

Explanation

At series resonance, the inductive and capacitive reactances cancel, leaving minimum impedance. Since current equals voltage divided by impedance, the current is maximum.
