LC Oscillations

A capacitor of capacity ' $C$ ' is charged to a potential ' $V$ '. It is connected in parallel to an inductor of inductance ' $L$ '. The maximum current that will flow in the circuit is

Show answer and solution

Answer: (c)

Maximum current flows when all electric energy becomes magnetic energy.
$\frac{1}{2}CV^2 = \frac{1}{2}LI_{max}^2$
$I_{max} = V\sqrt{\frac{C}{L}}$
So the answer is (c).
