An electrolytic capacitor definition is, it is a polarized capacitor whose anode has a higher or more positive voltage than the cathode. As the name suggests it is a polarized capacitor and an electrolytic capacitor function is, it uses an electrolyte to operate with a higher or more positive voltage on the anode than the cathode. Therefore, the anode terminal is denoted with a positive sign, while the cathode with a negative sign. Applying a reverse polarity voltage of 1 to 1.5 volts may destroy the capacitor and dielectric and the result is hazardous, leading to an explosion or fire.
An electrolytic capacitor uses an electrolyte, in the form of solid, liquid or gel – serves as cathode or negative plate to achieve much higher capacitance per unit volume. On the other hand, a positive plate or anode made of metal acts as an insulating oxide layer formed through anodization. This allows an oxide layer to work as the dielectric of the capacitor.
