In LCR series resonance circuit, choose the wrong statement.
- 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 \(X_L=X_C\).
Answer & Solution
Correct Answer
(B) At resonance, circuit is purely inductive
Step-by-step Solution
Detailed explanation
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.
