In LCR series circuit if the frequency is increased, the impendance of the circuit

A

increases

B

decreases

C

either increases or decreases

D

first decreases then becomes minimum and then increases.

Text Solution

Verified by Experts

The correct Answer is:
D
The impedance and current depend upon the frequency (f). As f is increased `omega L` is increased, `1/(omega C)` is decreased. At resonance the impedance is minimum.
