NEET Physics AC Voltage Assertion Reason Question
Assertion (A): In a purely capacitive AC circuit, the current amplitude is directly proportional to the frequency of the AC source. | Reason (R): The capacitive reactance in an AC circuit is inversely proportional to the frequency of the AC source.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The capacitive reactance Xc = 1/ωC is inversely proportional to frequency. Therefore, as frequency increases, Xc decreases, resulting in an increase in current amplitude (im = vm/Xc).
