Problem

Initially, a switch

S

is unshorted in the circuit shown in the figure on the right, a capacitor of capacitance

2 C

carries the electric charge

q_{0}

, a capacitor of capacitance

C

is uncharged, and there are no electric currents in both coils of inductance

L

and

2 L

, respectively. The capacitor starts to discharge and at the moment when the current in the coils reaches its maximum value, the switch

S

is instantly shorted. Find the maximum current

I_{\max }

through the switch

S

thereafter. <image_1>
