Physics-AC Voltage

NEET Physics AC Voltage Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

Assertion (A): In an AC circuit with a predominantly capacitive nature, the current leads the source voltage. | Reason (R): The phase angle ϕ\phi is positive when the capacitive reactance XCX_C is greater than the inductive reactance XLX_L.

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 A

Detailed Explanation

According to the NCERT context, if XC>XLX_C > X_L, the circuit is predominantly capacitive, leading to a positive phase angle ϕ\phi, which causes the current to lead the source voltage.
