The resonant frequency of a circuit is 1...

The resonant frequency of a circuit is 100 Hz. If the capacitor is replaced by another capacitor of capacity = 4 times the original capacity, then the resonant frequency will be

A

25 Hz

B

100 Hz

C

50 Hz

D

75 Hz

Text Solution

Verified by Experts

The correct Answer is:
C
`f = 1/(2 pisqrt(LC))` if C is increased to 4C then f will be `f/2` i.e. 50 Hz.
