NEET Physics Resonance Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Resonance in an ac circuit occurs only when both an inductor and a capacitor are present in the circuit. | Reason (R): In resonance, the voltages across the inductor and capacitor cancel each other out, being out of phase.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, resonance requires both an inductor and a capacitor; their voltages cancel each other out, which is why resonance does not occur in RL or RC circuits.
