In the a.c. circuit shown in the figure. The supply voltage has a constant r.m.s value `V` but varialbe frequency `f`. Resonance frequency in hertz is

A

10

B

100

C

1000

D

200

Text Solution

Verified by Experts

The correct Answer is:
C
`f_(0) = (1)/(2pi sqrt(LC)) = (1)/(2 pii xx sqrt((1)/(pi) xx (1)/(4 pi) xx 10^(-6))) = 1000 Hz`
