I've never really studied stun-guns, but what I remember, it uses a
quite high voltage, maybe 2 or 3kV at a very low current. I don't know
the frequency used, it could be just DC as using AC would enable risk
of getting muscles in a defribulation state. Especially the heart is
very sensitive to this.. people could die easily when their hearts get
into a spasm state..

probably it's the 7 Hz phenomena, the fequency earth resonates at. Can
someone reading this confirm it? I've read this a couple of times, but
don't have a reliable source.

it's simply how fast the chemicals Na and Ca react with eachother in
producing muscle force/ contraction. Most chemicals in our body have
these reaction times, it's all in the order of 50-200 ms. Is it a
coincidence film has at least 25 frames per second to show a seemingly
continuous motion? Lightbulbs don't noticably flikker? Musical patterns
fall in the same realm? No, it's just our bodies chemical speed. The 50
or 60 Hz of our electrical system was just emperically chosen by
looking at a lightbulb.. (anyone has a good reference on this? It's
almost certainly Tesla or Edison.)

well, in Europe at least (..) the electrical system has wires that
carry current back and forth. So we have a three phase system (3
wires), a null wire (carrying back current) and a ground wire. It's an
electrically closed system, without the ground, you can still turn on
your lights.. right?!
In Georgia I'm not sure...

don't have an answer about this.
