# Question

Consider the circuit shown in the figure below, where C1 = 8.00 µF, C2 = 6.00 µF, and ΔV = 22.0 V. Capacitor C1 is first charged by closing switch S1. Switch S1 is then opened, and the charged capacitor is connected to the uncharged capacitor by closing S2.

• Calculate the initial charge (in µC) acquired by C1.
• Calculate the final charge (in µC) on each capacitor.
• After a very long time, switch S1 is also closed. By what amount does the charge on the second capacitor change after S1 has been closed for a very long time?
