Explanation:
Detailed explanation-1: -A capacitor is a device that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance.
Detailed explanation-2: -EDLCs are charge storage devices, which are similar to lithium ion batteries in design and assembly. In general, EDLCs are composed of two electrodes, an electrolyte and a separator [27]. The separator electrically insulates the positive electrode and negative electrode in an organic electrolyte system.
