    Hey guys new to forum,I am a demolition engineer, and need to work with a bridgewire detonators, I’m used to pyrotechnic detonators but have to use bridgewire, how are capacitors charged to high voltage and amps. Like for example how do disposable camera use a flash that has 180v to 330v when they use a 1.5v AA battery as a power source.

    Any comment on explosives would be a no-no in here but since your query regards camera flash it might be ok to mention very basically how they work.
    A built in oscillator, thorugh a certain circuit, charges the cap to a predetermined high voltage dc.
    One can actually hear the oscillator running on some older cameras.
    This is then discharged into a neon type device creating the very short pulse of high level white light.
    The 1.5v or whatever, up to the 180 or 330v works much like a car ignition which boosts the 12v up to maybe 10Kv to 15Kv.

    As @Bluejets said ........
    A large value capacitor (uF and voltage rating) is charged up via an oscillator and then quickly discharged through the flash lamp

    Any other more detailed you can find online

    as for any other explosive related talk, we cannot entertain that on this forum, sorry,
    so this thread will be closed
