The energy stored in the capacitor increases from (dfrac{1}{2}Q_1V text{ to }dfrac{1}{2}Q_2V). The energy supplied by the battery = the energy dumped into the capacitor + the energy required to suck the dielectric material into the capacitor: [(Q_2-Q_1)V=dfrac{1}{2}(Q_2-Q_1)V+dfrac{1}{2}(Q_2-Q_1)V.nonumber]
18.5 Capacitors and Dielectrics
If a capacitor is charged by putting a voltage V across it for example, by connecting it to a battery with voltage V—the electrical potential energy stored in the capacitor is U E = 1 2 C V 2 . U E = 1 2 C V 2 .
How do capacitors work?
A capacitor attached to the flash gun charges up for a few seconds using energy from your camera''s batteries. (It takes time to charge a capacitor and that''s why you typically have to wait a little while.) Once the capacitor is fully charged, it can release all that energy in an instant through the xenon flash bulb. Zap!
