At the moment t = 0 , when the charge on the capacitor C 1 is zero, the switch is closed. If I 0 be the current through inductor at t = 0 , then for t 0 (initially C 2 is uncharged)

Question

At the moment t = 0 , when the charge on the capacitor C 1 is zero, the switch is closed. If I 0 be the current through inductor at t = 0 , then for t > 0 (initially C 2 is uncharged), maximum current through inductor equals I 0 2, maximum current through inductor equals C 1 I 0 C 1 + C 2, maximum charge on C 1 = C 1 I 0 L C 2 C 1 + C 2, maximum charge on C 1 = C 1 I 0 L C 1 + C 2

The maximum current through the inductor is I 0 . By conservation of energy, 1 2 L I 0 2 = 1 2 C 1 + C 2 V 2 V = L C 1 + C 2 I 0 Q 1 = C 1 V = C 1 I 0 L C 1 + C 2
