in a LCR circuit capacitance is chagned from C to 2C. For the resomat frequency to remain unchaged, the inductance should be chagned from L to

A

`4L`

B

`2L`

C

`L//2`

D

`L//4`

Text Solution

Verified by Experts

The correct Answer is:
C
`omega_(0) = (1)/(sqrt(LC))`
Now
`L'(2C) = LC rArr L' = (L)/(2)`
