Ans: An electrolytic capacitor is a polarized capacitor whose positive plate is built with a metal that creates an enclosed surface of oxide through anodization. The oxide surface plays the dielectric role of the capacitor. A hard or fluid electrolyte protects the layered oxide surface. It works as a negative plate or cathode.
