In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.

Like other conventional capacitors, electrolytic capacitors store the electric energy statically by charge separation in an electric field in the dielectric oxide layer between two electrodes.The non-solid or solid electrolyte in principle is the cathode, which thus forms the second electrode of the capacitor. This and the storage principle distinguish them from electrochemical capacitors or

The Electric Double-Layer Capacitor (EDLC), also commonly referred to as a supercapacitor or ultracapacitor, is a type of energy storage device. Unlike traditional capacitors that utilize the electrostatic field formed between conductive plates, EDLCs store energy by means of an electrochemical process, which allows them to possess a much higher energy
Supercapacitors are based on the same simple principles applicable to electrostatic capacitors where larger area plates and shorter distance between plates could give a higher effective capacitance. In supercapacitors, the electrical double layer formed next to a large-area electrode and an electrolyte is effectively used, and hence these devices are technically called electric

The capacitance of a capacitor is the amount of charge that can be stored per unit voltage. The energy stored in a capacitor is proportional to the capacitance and the voltage. When it comes to electronics, the significant components that serve as the pillars in an electric circuit are resistors, inductors, and capacitors.
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
