How Capacitors Work
The "plates" are two very thin sheets of metal; the dielectric an oily plastic film in between them. The whole thing is wrapped up into a compact cylinder and coated in a protective metal case. ... This is the basic principle behind the capacitor. Why do capacitors have two plates? Photo: The very unusual, adjustable parallel plate capacitor ...
When the supply is provided it gets charged. If the supply is of AC type for the positive part of the cycle it gets charged. The remaining …
Plastic film capacitor is a kind of capacitor with metal foil as electrode, which is overlapped with polyethylene, polypropylene, polystyrene, polycarbonate and other plastic films from both ends, and is wound into a cylindrical structure. ...

The self-healing capacitor is different, its medium is a single-layer PP film, and a thin layer (less than 1/100 μm) of metal is evaporated on the surface as a conductive electrode.When a voltage is applied, the electrical weak point of the PP film is broken down, and the breakdown current will pass through the breakdown point.
Capacitors working frequently get restricted because of different losses like surge or leakage. When leakage loss can be decreased by appropriate insulation using a ceramic or an epoxy coating, damage can be avoided because of short circuits. ... The polyester capacitor is designed with two metal plates where the polyester film is arranged ...
