At series resonance, voltage across L is____________voltage across C?

Correct answer: A. Equal to but opposite in phase to

  • A. Equal to but opposite in phase to
  • B. Equal to but in phase with
  • C. Greater than but in phase with
  • D. Less than but in phase with

Explanation

At series resonance, the inductive and capacitive reactances are equal, so their voltage magnitudes are equal. The inductor voltage leads current by 90° and the capacitor voltage lags by 90°, making them opposite in phase.
