Alternating Current · LCR and power

A capacitor C is first charged fully with potential difference of

V_0

and disconnected from the battery. The charged capacitor is connected across an inductor having inductance L. In t s 25% of the initial energy in the capacitor is transferred to the inductor. The value of t is s.
