An `L-C` circuit consists of a `20.0 mH` inductor and a `0.5 muF` capacitor. If the maximum instantaneous current is `0.1 A`, what is the greatest potential difference across the capacitor?

Text Solution

Verified by Experts

`1/2Li_(max)^2 =1/2CV_(max)^2`
`:. V_(max)=(sqrt(L/C)) i_(max)`
`=(sqrt((20xx10^-3)/(0.5xx10^-6)))(0.1)`
`=20V`
