Flashlights and Capacitors
Then the capacitor releases all that in less than a millisecond ($10^{-3}s$) or even just a few microseconds, so the flash bulb gets a massive jolt of energy. Secondly, the flash capacitor stores the energy at a much higher voltage: we''re talking about up to 1000V (typically around 300V), instead of the 6V from 4 AA cells.

Why might capacitors be used in camera flashes?
In a camera flash, the capacitor is charged up by a battery over a period of time. This charging process involves the movement of electrons from one plate of the capacitor to the other, creating a build-up of electrical potential energy. When the flash is triggered, the circuit is closed and the stored energy in the capacitor is rapidly released.

Battery–capacitor flash
A battery–capacitor flash (BC flash) is a flash photography system used with flashbulbs. Instead of relying directly on the current pulse ability of a photoflash battery to directly fire a flashbulb, a battery is used to charge a capacitor that is then discharged through the flashbulb.

What is a flash capacitor?
A flash capacitor is a type of capacitor used to store the energy that will power the flash. The PHOTOFLASH Capacitors are professionally manufactured and strictly controlled to ensure the best performance. Their unique internal structure allows for the repetitive pulsed discharge of the stored energy without stressing the capacitor.
What are photoflash capacitors?
Photoflash capacitors are used to store the energy that will power the flash. They are charged relatively slowly and discharged in a very short pulse duration by the flash. Capacitors of this type are common in applications like Medical IPL, Laser pumping, Coilguns and Railguns.
