A capacitor (5.70F) is connected in a series arrangement with a second capacitor (2.30F) and a 12-V

Question:

A capacitor (5.70μF) is connected in a series arrangement with a second capacitor (2.30μF) and a 12-V battery.
(a) How much charge is stored on each capacitor?
(b) What is the voltage drop across each capacitor? The battery is then removed, leaving the two capacitors isolated.
(c) If the smaller capacitor’s capacitance is now doubled, by how much does the charge on each and the voltage across each change?
