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. An electrolytic capacitor function 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, which is hazardous, leading to an explosion or fire.
An electrolytic capacitor uses an electrolyte in the form of solid, liquid or gel – serves as a 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. Allowing an oxide layer to work as the dielectric of the capacitor.
Due to the high capacitance value of this capacitor, it has the ability to store energy for a relative long time and release it instantly. This capacitor can operate at any voltage up to 63V, if this 63V is exceeded, the capacitor will likely blow-up r it will get damaged.
