Capacitors are electrical devices for electrostatic energy storage. There are several types of capacitors developed and available commercially. Conventional dielectric and electrolytic capacitors store charge on parallel conductive plates with a relatively low surface area, and therefore, deliver limited capacitance.
Capacitors as Energy Storage Another rather obvious use of the capacitors is for energy storage and supply. Although they can store considerably lower energy compared to a same size battery, their lifespan is much better and they are capable of delivering energy much faster which makes them more suitable for applications where high burst of power …
