In the circuit shown below, steady state was reached when the switch 's' was open. The switch was closed at t = 0. The initial value of the current through the capacitor 2 C is [Figure description: An 18 V source on the left in series with a 2 Ω resistor along the top wire. After the 2 Ω resistor, the circuit has two parallel branches: (1) a branch with a 4 Ω resistor in series with an inductor L down to the bottom wire, and (2) a branch of two capacitors in series (2 C on top, C below) down to the bottom wire. A switch s connects the midpoint between 4 Ω and L to the midpoint between the capacitors 2 C and C.]
