Those electric fly swatters that electrocute the fly, they're powered by 2AA batterys?

Question

How does it generate enough current to be any harm? at 3V over a large metal mesh(high resistance) the amps would be pitiful. the only way i thought of is using a transformer to lower the volts and make the amps higher, but it would have to lower it to stupidly low levels.

It's been bugging me(no pun intended :P) anyone shed some light on this for me?

Answer 1

The two AA cells power a high voltage generator.

Answer 2

When you think about it, it takes 6 milliamps across the human heart to stop it. The insect's body is much smaller, so the amperage isn't scattered as much and the insects vital organs are much smaller and therefore probably cannot handle anywhere near 6 miliamps. It would only need that pitiful amperage to kill one.
