Question

Given below are two statements.

Assertion : When the capacitive reactance is smaller than the inductive reactance, in a series AC RLC circuit, voltage leads the current.

Reason : In series AC RLC circuit, inductive reactance is always greater than capacitive reactance.

Based on the above statements, choose the correct alternative.

• A. Both assertion and reason are true, and the reason is a correct explanation of the assertion.
• B. Both assertion and reason are true, but the reason is not a correct explanation of the assertion.
• C. Assertion is true, but the reason is false.
• D. Assertion is false, but the reason is true.

Answer 1

The correct option is C Assertion is true, but the reason is false.

A series AC RLC circuit is shown below.


When the capacitive reactance is smaller than the inductive reactance, in a series AC RLC circuit, voltage leads the current because the affect of inductance is more than the affect of capacitance.

In a pure inductive AC circuit, voltage leads the current.

Also, capacitive reactance can be greater than the inductive reactance.

Therefore, the assertion is true, but the reason is false.

Hence, option $\left(C\right)$ is the correct answer.
