A capacitor of capacitance C is given charge Q and then connected in parallel to a coil of inductance L. There is no resitance in the circuit. When the charge on the capacitor becomes zero, the current in the coil will be

A capacitor of capacitance Chas initial charge Q_0 and connected to an inductor L as shown. At t=0 switch S is closed. The current through the inductor when energy in the capacitor is three times the energy of inductor is

In the circuit shown, a capacitor charged to a potential difference V_(0) is connected to an uncharged capacitor through a resistor at t=0 , by closing the switch. Find current in the circuit as function of time. .

Three identical large plates are fixed at separation of d from each other as shown in figure. The area of each plate is A. Plate 1 is given charge +Q while plates 2 and 3 are neutral and are connected to each other through coil of inductances L and switch S. If resistance of all connected wires is neglected the maximum current flow through coil after closing switch is ( C=epsilone_0 A/d ) (neglect fringe effect)

Two capacitors of capacitance C and 3C are charged to potential difference V_(0) and 2V_(0) , respectively, and connected to an inductor of inductance L as shows in Fig. Initially, the current in the inductor is zero. Now, switch S is closed. Potential difference across capacitor of capacitance C when the current in the circuit is maximum is
