An 817-f capacitor is fully charged by a 325-v battery, Ask an Expert

Academics

An 8.17-?F capacitor is fully charged by a 325.-V battery, which is then disconnected. Next, the capacitor is connected to an initially uncharged capacitor of capacitance C, and the potential difference across it is found to be -55. V.

a) What is C?

b) How much energy ends up being stored in the second capacitor?
