Question 1

In the given network, initially the switch is in the position 1, but at t = 0, the switch is moved to position 2 and the capacitor starts discharging. Find the discharging current i(t).

Question 2

In the circuit shown in the figure, the current source I = 1A, voltage source V = 5H, R1 = R2 = R3 = 1 W, L1 = L2 = L3 = 1H, C1 = C2 = 1 F.
If the circuit is reached in steady state.The current (in A) through R3 and the voltage source V respectively will be
