An A.C. circuit consists of inductor of inductance `125mH` connected in parallel with a capacitor of capacity `50muF`. Determine the resonant frequency.

Text Solution

Verified by Experts

Given: `L=125mH`, `C=50muF`
Resonant frequency,
`f=(1)/(2pisqrt(LC))`
`=(1)/(2pisqrt(125xx10^(-3)xx50xx10^(-6)))`
`=(1)/(2pisqrt(0.00000625))`
`=(1)/(0.0157)`
`=63.69Hz`
