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.

Supercapacitors vs. Batteries: What''s the Difference?
The big difference is that capacitors store power as an electrostatic field, while batteries use a chemical reaction to store and later release power. Inside a battery are two terminals (the anode and the cathode) with an electrolyte between them. An electrolyte is a substance (usually a liquid) that contained ions.

The amount of energy stored in a capacitor depends on its capacitance, measured in farads, and the voltage across it. The formula for calculating the energy stored in a capacitor is: E = (1/2) x C x V^2. Where E is the energy stored in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.
