Capacitors
A practical capacitor is made from two conducing surfaces separated by an insulator. To understand how it works, we take the simple case of two rectangular metal plates in a vacuum shown in Fig. 7.1 and apply a voltage between the two plates. This will create an electric field between the inner surfaces of the plates which will try to repel …
Introduction to Capacitor Technologies
Depending on the dielectric and electrode construction, it may be possible for a capacitor to "heal" itself. For example, film and paper capacitors with very thin electrodes (1/1000th the diameter of a human hair) are able to self-heal. This self-healing occurs as the large current flowing through the breakdown area heats up the electrode ...

At present, the important capacitor technologies are impregnated foil-polymer film (for high voltage, high current), metalized film, ceramic, electrolytic, and electric double layer, although metalized paper is still used occasionally in "soggy foil" designs, i.e., self-clearing, fluid-impregnated, high-voltage capacitors. Each of these major technologies faces …
