An electrolytic capacitor, also called e-cap, is a polarized capacitor. In this capacitor, one plate is coated through electrolysis with an oxide to act as a dielectric, while the other plate is replaced by an electrolyte.
Solid, liquid, or gel electrolytes can be used as the cathode or negative plate in these capacitors, which protects the oxide layer. Generally, electrolytic capacitors can bear products with
