Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
The key difference between the two is that batteries have a higher density (storing more energy per mass) whilst capacitors have a higher power density (releasing and store energy more quickly). Supercapacitors
Capacitors are essential components in the world of electronics, used in everything from small gadgets to large industrial machines.
