To reduce the resonant frequency in an LCR series circuit with a generator,

A

the frequency of the generator should be reduced

B

another capacitor should be connected is parallel with the first capacitor

C

the iron core of the inductor should be removed

D

the dielectric in the capacitor should be removed

Text Solution

Verified by Experts

The correct Answer is:
B
`f=1/(2pisqrt(LC))`
`therefore` To reduce f either L or C or both has to be increased.
