Options:
  • A At resonance, impedance is minimum.
  • B At resonance, circuit is purely inductive
  • C At resonance current has a maximum value.
  • D Resonance occurs at $X_L=X_C$.

The correct answer is: At resonance, circuit is purely inductive
Concept: In LCR series circuits, resonance occurs when the value of inductive and capacitive reactances have equal magnitude but have a phase difference of $180^{\circ}$. Thus, they cancel each other. The circuit is purely resistive at resonance.
