Ok , I got the privlege of working with a master electrician to wire my home.
I know the theory and how to rig electrical circuits and electronic circuits.
However one day rigging the house we didn't shut the power completly off
just working with live wires.....
He being very experience working doing this stuff for 30 years or so.
And we got into an argument.
I said it was ok to touch the green or white ground wires even if the wires are live because your at the same potiential and your not completing the circuit. (he agreed and I demonstrated)
But then I said if you are touching the black wire you are going to get shocked because this is at a different potiential and you are closeing the circuit from the hot to ground...etc
He disagreed and said I hold it all the time when doing electric work on 120vac. He said you just cann't hold the white/green ground wires and the hot black or red wires at the same time. ( I agree with getting shocked if you hold the two wires but what I don't agree with is just by standing on the ground and holding just the black you are completing the circuit so you should get shocked.)
So he demonstrated it by holding the hot wire to much my suprise nothing happened ... he finely convinced me to try it so I did.
We are both pretty expereniced in electrical things ( me the theory more so and low voltage electronic circuits ,PCB boards ...etc him high voltage power ...stuff)
But the theory would say that your completing the circuit and current should flow thru you zapping you.... (governed by ohms law)
120volts = current * human body resistance
I am not sure what the average human body resistance....
The only thing I can think of is that are bodies where providing enough resistance to limit the current into an exceptable range so we couldn't even feel it flowing thru us (and it was to small to hurt us )
Because if this wasn't true then ohms law would be for ****.....
Also we both had rubber shoes on would this provide enough resistance
to be almost like an open circuit or what this is bothering me.
If we took are shoes off would this be a different story. <--(we don't dare do this )
So is it because the rubber shoes are the defining factor ???
Because if you hold the white and black at the same time current will have less human body resistance to flow thru to get back to the ground wire.
But in the case of holding just one hot wire are human body resistances is increased + the rubber boot resistance...
This is all I can think of
Just need clarity to know for sure definitley not going to try it ....
But this is the only way I can see the theory working....ohms law ...etc
He did keep saying you just cann't ground your self and you will be alright with "120 vac"
But I thought we are on the ground to begin with <--you mean to tell me just having some little piece of rubber under you your ok?
Thanks for input.
But either way you are always on the grounded I am justing thinking that it is the amount of resistance you provide defineds weather your going to get shocked.... since holding the white and black at the same time the electricity will just have to flow thru your arms and not thru your whole body out your rubber shoes ....
