tactical blinding device

Resistors in series:

R

Resistors in parallel:

1/R

Capacitors are the opposite, so series capacitors use the same equation as the parallel resistor equation (but with capacitance values) and parallel capacitors use the series resistors equation.

stick to the topic, and negative posts aren't helpful

If you make this a single use device, and an defence weapon to be used at night, from maybe a foot away, then yeah it could work 3 flash bulbs in a row going down, 3 capacitors per bulb, 1 battery per bul, give it 30s to charge tho

but at night when already dark could be disorientating

Meh
I'll stick with drwing out a modified flashlight with slow flash powder cartridges, easy to fit in the bulb slot, or something like that, ... yes, just like a good old fashion camera.

Could you build a small flash as in kno3+mg device wich in subgram amounts was ignited in a machine gun type way?

Yes, but he wants an electronic way. You would also have to restock a chemical flash device after every shot.

I would use flour throwqen in the eyes after a very bright flash becuuse flour in the eyes hurts realy badly and temperarily blinds you.
