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 \( t \) \( \text{s} \) \( 25\% \) of the initial energy in the capacitor is transferred to the inductor. The value of \( t \) is ______ \( \text{s} \).
