The equivalent capacitor : 1/C A = 1/C 1 + 1/C 2 = 1/20 + 1/20 = 2/20 . C A = 20/2 = 10 µF Capacitor C 1 and capacitor C 2 are connected in series. $\endgroup$ – Alfred Centauri Apr 24 '18 at 12:02 $\begingroup$ Pedantic comment: the energy stored in the capacitor is, as you write, $\frac{1}{2}CV^2$ but the work done by the battery in charging the capacitor is (ideally) larger by a factor of 2. Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Qand voltage Von the capacitor. As the capacitor is being charged, the electrical field builds up.
When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.
3.00\text{ mm}. We must be careful when applying the equation for electrical potential energy ΔPE = qΔV to a capacitor.
