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

Options

A. A
B. B
C. C
D. D

Answer

C

Explanation

In series resonance circuit, `omega L = 1// C`
`:. Z = sqrt(R^(2) + (omega L - (1)/(omega C))^(2)) = R`
Assertion is ture. But reason is false as inductive reactance is only to capacitive reactance.
