WARNING. DO NOT TRY TO DO THIS - IT COULD KILL YOU!
Just out of interest, I made a suitable arrangement
* to determine the amount of a.c. current from a 120-v.a.c. r.m.s. source, through one hand of my body and out of the other, at which point my reaction would be "Ouch!" and thus rapidly let go. To monitor the current I used my trusty AVO 8.
Results.
At 1 mA, it was a bit more than a slight tingle.
At 2 mA, it was "Ouch!" - and I rapidly let go.
Currents greater than 2 mA were not used!
I measured the resistance between my two hands: 100 kΩ; 120-v. and 100 kΩ = 1.2 mA. I was surprised that a current as small as 2 mA caused the reaction that it did. And it makes me think a bit about RCDs that have a trip current in the range 20 to 30 mA . . . . .
* The details of which I am
not going to describe, in order to dissuade anyone from doing this experiment.
