A 40 $\mu$ F and a 10 $\mu$ F Capacitor Are Connected in Parallel and Both Are Charged

Short Answer

A 4.0 $\mu$ F and a 1.0 $\mu$ F capacitor are connected in parallel and both are charged with a 12. volt battery. They are disconnected from the battery and reconnected positive side of the 1st to negative side of 2nd, and neg. side of 1st to pos. side of 2nd.
(a) How much was each charged when connected to the battery?
(b) After reconnecting, how much charge is stored?
(c) What potential exists across the final parallel combination?
