Introduction to Capacitors, Capacitance and Charge

Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.

How does a capacitor work?

A capacitor is a bit like a battery, but it has a different job to do. A battery uses chemicals to store electrical energy and release it very slowly through a circuit; sometimes (in the case of a quartz watch) it can take several years. A capacitor generally releases its energy much more rapidly—often in seconds or less.

Do capacitors automatically release their energy over time?

Capacitors have ''leakage resistors''; you can picture them as a very high ohmic resistor (mega ohm''s) parallel to the capacitor. When you disconnect a capacitor, it will be discharged via this parasitic resistor. A big capacitor may hold a charge for some time, but I don''t think you will ever get much further than 1 day in ideal circumstances.
