NEET Physics Resonance Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 12
Given below are two statements:
Statement I: When the frequency of an a.c. source in a series LCR circuit increase, the current in the circuit first increases, attains a maximum value and then decreases.
Statement II: In a series LCR circuit, the value of power factor at resonance is one. In the light of given statements,
choose the most appropriate answer from the options given below:
A
Statement I is incorrect but Statement II is true
B
Both Statement I and Statement II are false
C
Statement I is correct but Statement II is false
D
Both Statement I and Statement II are true
Correct Answer
Option 4
Detailed Explanation
In a series LCR circuit, the current is maximum at resonance, and the power factor is one at resonance, making both statements true.
