Physics-Power in AC Circuits
NEET Physics Power in AC Circuits Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The average power dissipated in an AC circuit is given by P = VI cos φ. | Reason (R): The average power depends on the phase difference between voltage and current.
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
The average power in an AC circuit is given by P = VI cos φ, where φ is the phase difference between voltage and current, explaining why power depends on this phase difference.
