Principles and applications of electrochemical capacitors
Abstract. Electrochemical capacitors (EC) also called ''supercapacitors'' or ''ultracapacitors'' store the energy in the electric field of the electrochemical double-layer. Use of high surface-area electrodes result in extremely large capacitance. Single cell voltage of ECs is typically limited to 1–3 V depending on the electrolyte used.
How do capacitors work?
A capacitor attached to the flash gun charges up for a few seconds using energy from your camera''s batteries. (It takes time to charge a capacitor and that''s why you typically have to wait a little while.) Once the capacitor is fully charged, it can release all that energy in an instant through the xenon flash bulb.

Capacitors Basics
In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. Initially.
