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.

Energy Stored in Capacitors | Physics
The energy stored in a capacitor can be expressed in three ways: Ecap = QV 2 = CV 2 2 = Q2 2C E cap = Q V 2 = C V 2 2 = Q 2 2 C, where Q is the charge, V is the voltage, and C is the capacitance of the capacitor. The energy is in joules for a charge in coulombs, voltage in volts, and capacitance in farads. In a defibrillator, the delivery of a ...
