In an LCR series circuit the capacitance is changed from `C` to `4C` For the same resonant fequency the inductance should be changed from `L` to .

A

2 L

B

`L/2`

C

4L

D

`L/4`

Text Solution

Verified by Experts

The correct Answer is:
D
We know that,
In L-C-R circuit, `f=1/(2pi)sqrt(1/(LC))`
For the same resonant frequency, the inductance should be changed from L to `L/4`
