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.
