An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged an…

Electrolytic capacitors contain a liquid electrolyte that acts as the dielectric, allowing for higher capacitance. The electrolyte is typically a corrosive substance, and if the capacitor experiences excessive voltage, heat, or aging, the electrolyte can break down and release gas. This gas build-up can cause pressure to build within the ...
Capacitors 101: What Do Capacitors Store in Electronic Circuits?
A capacitor is a two-terminal electrical component used to store energy in an electric field.
