The switch S in the circuit shown below has been open for a long time when, at time t = 0, it is closed. The values of the circuit elements are: V = 12 V, R1 = 110 Ι̩, R2 = 220 Ι̩, R3 = 330 Ι̩, C1 = 40 μF and C2 = 80 μF.
What is Q2final, the charge on C2 a long time after the switch is closed? Q2final =
