Senile lloyd wants to know how high voltage is safer than low. Anyway, you apparently you never took the hospital electrician's

advice of referring you to the NEC manual.

A taser is 50,000 volts. Thats high. The amperage there isn't a factor. A stun gun is 900,000 volts.

outta tell you right there that voltage isn't what harms. It's low
voltage with higher amps that is harmful.

Talk to a physicist or a doctor your own damn lazy self if you want to know what of two voltages fits your satisfaction of what's safer.

I'm rather disappointed that I have not been able to educate you about
how this all works. I think if you could just get a good understanding
of ohms law, you would see immediately were you are mistaken.
When I got into this thread I was trying help you understand and prevent
others from getting incorrect information.

I would hate to confuse you with terms that aren't in your NEC
manual, like output impedance and current limited or short pulses or the
fact that a stun gun has electrodes that are about 2 inches apart, so
the current has little chance to go to the heart.
Here is a page that suggests stun guns are limited to 3 ma or 4 ma and
most are limited to 1 ma to 2 milliamps.
Police tasers use darts which actually pierce the skin that reduce the
resistance of the circuit through the body so the voltage does not need
to be as high to deliver the same current as if it was on the outside of
the skin.

How do you reconcile the fact that a car battery can deliver 600 amps
but you can hold on to the terminals and survive?

Answer: It's because the voltage is low, and will not cause a current
large enough to cause harm. If you raise it to say 40 or 50 volts you
might be able to start to feel it tingle. If the voltage gets much
higher, you are going to want to get loose. The bottom line is the
current is dependent on the resistance between your skin and the
electrode you touch and the voltage.

These sentences might help.
The amount of current depends on the voltage and the resistance of the
circuit.
If the voltage is higher with a constant resistance more current will flow.
With a constant voltage, the current is dependent on the resistance,
with a lower resistance more current will flow, with a higher resistance
a lower current will flow.
