A capacitor of capacitnafe `2muF` is charged to a potential difference of 12V. It is then connected across an inductor of inductance 0.6mH. The current in the circuit when the potential difference across the capacitor is 6V is

Text Solution

Verified by Experts

The correct Answer is:
`(6)`
From energy conservation: `(1)/(2) CV_(0)^(2) = (1)/(2) Cv^(2) + (1)/(2) LI^(2)`
`rArr (1)/(2) xx 2xx 10^(-6) xx 12^(2) = (1)/(2) xx 2 xx 10^(-6) xx 6^(2) + (1)/(2) xx 6 xx 10^(-6) I^(2)`
`rArr I = 6 A`
