In LCR series resonance circuit, choose the wrong statement.

Options

  1. AAt resonance, impedance is minimum.
  2. BAt resonance, circuit is purely inductive
  3. CAt resonance current has a maximum value.
  4. DResonance occurs at X_L=X_C .

Correct answer

B. At resonance, circuit is purely inductive

Step-by-step 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^ . Thus, they cancel each other. The circuit is purely resistive at resonance.
