Charge and stored energy for capacitors
Pick one of the two capacitors (either one -- it doesn''t really matter which). You''ve already calculated the amount of charge on that capacitor before they were connected together. Now consider that instead of connecting them together, calculate how much charge would be on that capacitor if you merely change the potential to 8.65 V.

Lesson Explainer: Capacitors in Series and in Parallel | Nagwa
Also, remember that the amount of charge that flows through a circuit branch is the product of the current in the branch and the time for which the charge flows. Thus, when the circuit is closed and the capacitors are able to charge up for some time, the charges on all capacitors ( 𝑄 and 𝑄 here) add up to the total charge in the entire circuit, 𝑄 t o t a l, as …
How is the "charge on a capacitor" defined when two plates are unequally charge…
The "charge on a capacitor", in terms of circuit theory, is equal to the amount of charge that would flow down a wire connecting one plate to the other, if a wire were so connected, until the current stopped. The current will …

Your answer is wrong in the sense that the charge will not be equally divided between the plates of the two capacitors. And the reason is that the capacitors have different capacitances. In this case you need to apply Kirchoff''s voltage rule to get the correct equation.

Energy Stored in a Capacitor | Brilliant Math & Science Wiki
A capacitor is a device for storing energy. When we connect a battery across the two plates of a capacitor, the current charges the capacitor, leading to an accumulation of charges on opposite plates of the capacitor. As charges accumulate, the potential difference gradually increases across the two plates. While discharging, this potential difference …

Why do the two plates of a capacitor store equal amounts of charge?
Charging a capacitor simply applies a voltage to both sides (i.e. it doesn''t add or remove charge), so the capacitor must remain net neutral. In other words, the two plates must store equal amounts of charge. Share Cite Improve this answer Follow 60 …
