i am curious as how stun guns create very high voltage. I have seen them marketed to make as high at 2 million volts. does anybody have a clue?

Just an induction coil. 20 kV at most. You can't generate 2 MV with something much smaller than a house.

The marketing is of course far from the truth when it comes to the voltage ratings, they derive it from very loose handling of mathematics... and a bit of free interpretation I guess ;)

I was searching for the post (within a thread) for awhile sometime ago. There IS a cute little way they don't get slammed for false advertising.
The answer is out there.... ("X-Files theme song" in background)

I think you could generate 2 million volts with light current from something about the size of a closet or a clothes washing machine..... Doesn't HAVE to be house. tongue

Its the volts that jolts but the mills that kills. its prabably a tiny flyback that operates at a low frequency so that the skin effect is eliminated and the victim can feel the shock

The skin effect doesn't come into play until about 4MHz. (at least on flesh)

It is just a stepup transformer and inverter, which charges a cap which is discharged through another stepup transformer. It isn't constant current like a transformer, it is a pulse transformer like in a camera. You can compare it to a camera, the few kv trigger voltage is from a cap charged by a stepup transformer, which discharges into a pulse transformer.

The frequency was just beyond your threshold of perception... Link2
