Physics-Power in AC Circuits
NEET Physics Power in AC Circuits Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): In an AC circuit containing a pure inductor, the average power consumed over a complete cycle is zero. | Reason (R): The inductive reactance in an AC circuit is analogous to resistance in a DC circuit, both limiting current flow.
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, but R is true.
Correct Answer
Option B
Detailed Explanation
The average power consumed by an inductor over a complete cycle is zero because the average sin(2ωt) is zero. Inductive reactance is similar to resistance in limiting current, but it does not explain why the average power is zero.
