Which of the following curves represents the variation of impedence `(Z)` with frequency `f` in series `LCR` circuit?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Impedance at resonant frequency is minimum in series LCR circuit.
So , `Z = sqrt(R^(2) + (2pifL - (1)/(2pifC))^(2))`
