I've always been told that Volts don't kill you, Amps do. I have never quite accepted that explanation and I will tell you why, so you can correct me.
They say that 4mA across your heart will kill you
example #1: A tazer. They will tell you that a tazer will pass something like 50KV through your body but it doesn't put out enough amperage to kill you. What? It's a current limited voltage source, correct? So if your body's resistance is low enough to load the tazer past it's limit (assuming it's limit is somewhere below 4mA to make it nonlethal, shouldn't be too hard to load past that), then it's not putting out 50KV anymore.
Example #2: A car battery. the battery in my truck can supply around 600amps at short, yet I can grab ahold of both terminals and not die. plenty of amps there, but they didn't kill me.
The way I see it, in order to kill you, The voltage needs to be high enough to create a current above the 4 ma given the very high resistance of your body and the source needs to be able to maintain that voltage (in order to maintain that current) ,So it's a power thing and not solely an amperage thing, and a significantly high voltage needs to be involved.
Now somebody please tell me where I am screwing this up.
