In LCR series resonance circuit, choose the wrong statement.

In LCR series resonance circuit, choose the wrong statement.
  1. At resonance, impedance is minimum.
  2. At resonance, circuit is purely inductive
  3. At resonance current has a maximum value.
  4. Resonance occurs at $X_L=X_C$.

Solution

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.
