Directions : In the following questions, A statement of Assertion (A)...
Understanding the Assertion (A)
When dealing with a series LCR (Inductor-Capacitor-Resistor) circuit, the behavior of the circuit is determined by the relationship between capacitive reactance (XC) and inductive reactance (XL).
- Capacitive Reactance (XC): This opposes the change in voltage.
- Inductive Reactance (XL): This opposes the change in current.
When XC < xl,="" it="" indicates="" that="" the="" inductive="" reactance="" dominates,="" causing="" the="" circuit="" to="" behave="" like="" an="" />
Assertion Explanation
- In this scenario, the e.m.f. (electromotive force) or voltage actually leads the current. This is a key characteristic of inductive circuits.
- Therefore, Assertion (A) is true.
Understanding the Reason (R)
The angle φ, which represents the phase difference between voltage and current, is given by the formula:
- tan φ = (XL - XC) / R
Here, R represents the resistance in the circuit.
- If XL > XC: The circuit is inductive, and voltage leads current.
- If XC > XL: The circuit is capacitive, and current leads voltage.
Reason Explanation
- The formula correctly describes the relationship of the phase angle in an LCR circuit where the behavior of the circuit is dependent on the difference between XL and XC.
- Thus, Reason (R) is also true and provides a valid explanation for Assertion (A).
Conclusion
- Given that both Assertion (A) and Reason (R) are true, and R correctly explains A, the correct answer is option (A): Both A and R are true and R is the correct explanation of A.

- Thus, Reason (R) is also true and provides a valid explanation for Assertion (A).
Conclusion
- Given that both Assertion (A) and Reason (R) are true, and R correctly explains A, the correct answer is option (A): Both A and R are true and R is the correct explanation of A.
