My primary education is not the electrical/electronic field, but I do

have a science background. What I am trying to get my head around is

something I heard from a friend who said, "It is not the voltage that

kills/hurts but the amperage". I understand that statement to a

certain point, but not satifactorily enough. I get the idea of the

Coloumb -- it is the most straightforward to understand. The amount of

"charge carriers" (electrons). I find the concept of Amperage fairly

well straightforward also. A rate at which these charge carriers pass

an arbitrary point (or plane). It makes fairly well good sense that

difference of rate of these "passing/moving through" (a current) the

body will give differences of intensity of the "shock". Now, when I

think of the formula E=I/R, I imagine limits of the numerator and

denominator. You could have a very small current, but if the

resistance is nearing zero, the EMF/voltage will approach infinity or

at least be very high. So if you have, say, 3000 volts, and the

resistance is very low, so that the current is low, a very small

amperage would flow through the body when you touch the terminals of

the object of energy in question with that voltage ( a short?), so the

coloumbs (amount of charges) is low. Now 3000 volts should fry

somebody in normal circumstances. This, finally, leads me to the

question; if a battery/generator or whatever source has 3000 volts, is

their a minimum practical size it has to be and therefore a minimum

Coloumbs it must have?
