DC/AC neither will touch you if you are not grounded because electricity always looks for the shortest path to ground. I have had shocks from old bell telephone equipment (6VDC) it just tingled but it shocked none the less. For AC voltage frequency matters and for both Amperage matters, volts won't kill but amps sure as hell will. I have been hit with everything from 6VDC to 440 3 phase and the one that hurt most was 120V at 400hz. Capacitors are DC voltage when discharging, have you ever caught a 1 farad capacitor, they will knock you flat on your ***.

 

i dont know **** about electricity, i know when i was 10 i somehow got my thumb behind a socket that was in the basement and it shocked the **** out of me, i couldnt let go and my arm was like iron and once i did get released my thumb was burnt and hurt like hell the rest of the day. No idea if that was 240V for like a drier or not. I was too young to look at it i just ran off.

 

This is FALSE! Electricity flows towards the direction of the least potential, and the ground is zero potential. HOWEVER, if you are totally ungrounded and touch 2 conductors of different potential, you WILL BE ELECTROCUTED!

 

You can continue to believe that all you want. The truth is, the damage done to your body is a direct result of current flow. Current flow varies per the rules of ohms law. Therefore, higher voltage=more current flow=more damage, whether its ac or dc. Ever touch a cattle fence? Many cattle fencers are dc. You can definitely tell when they "touch" you.

 

You keep moving the goal post.
No kidding, the Secondary spike will make you jump such as ignition voltage, or cattle fence can give ya whack.
However, I assure you I can go out in my bare feet in the wet grass and grab a 12 or 24 volt DC battery any way you want it and most people will not ever feel it.
In fact, I have not ever run onto anyone that said they got buzzed by 12 or 24 DC current. ( not stepped up)
That has been my experience.
yours seems to be different.
This is not the mountain I am going to argue for.
Believe what you wish.
It is too trivial for me to banter about.

 

The reason is that there is too much resistance for the current to travel through unless you have wet hands touching each other and you touch both leads of the battery.

 

If you have low resistance (wet hands) or higher voltage (48V, 120V, 240V ) AC or DC, current will flow.


During NORMAL conditions, kinglide549 is right. Nobody is getting shocked from 12VDC

I've grabbed right onto 120v when I was an electrician and felt nothing. New boots, dry floor, etc. and even the odd time on 240v. One time I was in a wet basement and
got tickled with 240v while kneeling on concrete. Not a smart move. Duh

(you feel a small tingle on your tongue with a 9v battery as the resistance across 1" of your WET tongue is quite low, a few hundred Ohms probably, so current flows.)
However, put that same 9v battery on your DRY arm, leg, head(full full head of hair) and you'll feel nothing.

Buddy is not getting shocked with 12vdc unless he is sopping wet with a conductive fluid.

 

If you look back, I agreed with him that low voltage dc wont do anything. When he made the blanklet statement that dc current can't hurt you, I interjected that at higher voltages it is just as dangerous as ac. Then, he claims that he can hook 50 12v batteries together in series and the potential created wont be dangerous? If you hook 50 batteries together in series,(negative of one battery to positive of the next) you would get over 600v dc from the 1st battery pos. To the last battery neg, easily enough to kill someone. I don't care what you say, this statement of his was DEAD WRONG. And he accused me of moving the goalpost? All I'm doing is trying to stop the spread of downright dangerous information. If some dipstick reads this thread and gets themselves killed thinking high voltage dc isn't dangerous, I've done all I can to try to properly educate them. The rest is in their hands.

 

That is all we can do, try to educate and let the chips fall where they will.
