Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : In a series LCR circuit at resonance, the voltage across the capacitor or inductor may be more than the applied voltage.
Reason (R) : At resonance in a series LCR circuit, the voltages across inductor and capacitor are equal & (180^{\circ}) out of phase.
In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
B. Both (A) and (R) are true and (R) is NOT the correct explanation of (A).
Step-by-step solution
Assertion (A) is true because at resonance, the voltage across the capacitor or inductor can exceed the applied voltage. Reason (R) is also true, as the voltages across the inductor and capacitor are equal in magnitude and (180^{\circ}) out of phase at resonance. However, (R) does not explain why the voltages can be greater than the applied voltage; it simply describes their relationship.
