A circuit of negligible resistance has an inductane of 10 mH and a capacitance of 0.1 `muF`. The resonant frequency of the circuit is nearly

A

5 kHz

B

2.5 kHz

C

31.4 kHz

D

3.14 kHz

Text Solution

Verified by Experts

The correct Answer is:
A
`f=(1)/(2pisqrt(LC))`
`=(1)/(2xx3.14xxsqrt(10xx10^(-3)xx0.1xx10^(-6)))`
`=5.036kHz`
`~~5kHz`
