How to Charge a Capacitor
How to Charge a Capacitor. Charging a capacitor is very simple. A capacitor is charged by connecting it to a DC voltage source. This may be a battery or a DC power supply. Once the capacitor is connected to the DC voltage source, it will charge up to the voltage that the DC voltage source is outputting.
18.5 Capacitors and Dielectrics
Squeezing the same charge into a capacitor the size of a fingernail would require much more work, so V would be very large, and the capacitance would be much smaller. Although the equation C = Q / V C = Q / V makes it seem that capacitance depends on voltage, in fact it does not. For a given capacitor, the ratio of the charge stored in the ...

How Capacitors Work
What does a capacitor do? A capacitor allows for the very quick release of electrical energy in a way that a battery cannot. For example, the electronic flash of a camera uses a capacitor.
Capacitors
A capacitor''s capacitance -- how many farads it has -- tells you how much charge it can store. How much charge a capacitor is currently storing depends on the potential difference (voltage) between its plates.

Expressed otherwise, the work done in separating the plates equals the work required to charge the battery minus the decrease in energy stored by the capacitor. Perhaps we have invented a battery charger (Figure (V.)19)! (text{FIGURE V.19}) When the plate separation is (x), the charge stored in the capacitor is (Q=frac{epsilon_0AV}{x}).
