A capacitor of capacitance C is given charge Q and then connected in parallel to a coil of inductance L. There is no resistance in the circuit. When the charge on the capacitor becomes zero, the current in the coil will be(a) Q√L/C (b) Q/√LC (c) Q√C/L (d) zero

Answer»

Correct Answer is: (b) Q/LC 

The initial energy stored in the capacitor is Q2/2C.

When this energy gets transferred to the coil, carrying current i, 1/2 Li2 = Q2/2C.
