The capacitor for capacitance C can be charged ( with the help of a resistance R) by a voltage source V, by closing switch S_(1) while keeping switch S_(2) open. The capacitor can be connected in series with an inductor 'L' by closing switch S_(2) and opening S_(1). After the capacitor gets fully charged S_(1) is opened and S_(2) is closed so that the inductor is connected in series with the capacitor. Then,

Answer»

at t=0, ENERGY stored in the CIRCUIT is purely in the FORM of magnetic energy
at any time `tlt 0`, current in the circuit is in the same DIRECTION.
at `tgt0`, there is no exchange of energy between the inductor and capacitor
at any time `t gt0`, instananeous current in the circuit will have MAXIMUM value `Vsqrt(( C)/(L))`, where C is the capacitance and L is the inductance.
