Assertion : In series LCR resonance circ...

Assertion : In series LCR resonance circuit, the impedance is equal to the ohmic resistance.
Reason : At resonance, the inductive reactance exceeds the capacitive reactance.

A

If both assertion ans reason are true ans reaason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion istrue but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C

In series resonance circuit, inductive reactance is equal to acpacitive reactance.
i.e., `omega L = (1)/(omega C) therefore Z = sqrt(R^(2)+(omega L-(1)/(omega C))^(2))=R`
