Same as if you grabbed a hold of an electric fence, you still get zapped even though you're wearing shoes.

My guess is that when you touched it, the fence was between pulses.

Unless it had a non-pulsing control unit. What say you?

Birds can sit on a single high voltage wire and not be affected because there's just a single contact point. You could hang on the same wire and do pull ups safely as long as no other points are touched. To excite voltage there must be a drop or difference between two points like a ground provides. Even though both of our hands are on the same wire, there is no circuit because there isn't a voltage drop. Electricity takes the easiest path.

When we grab an electric fence, we become the easiest path to ground and get zapped.

Typical rubber soled shoes will help but not stop voltage because of the dirt/sweat/contamination that builds up in the soles.

At least that's my theory as I remember from school 20 years ago... :)

I would say you win this bet on a technicality. While whizzing on fence can shock the hell out of you, electrocution refers to death. No one has ever survived electrocution because by definition it means death by electricity.

Just like if you drown. You're dead. There's near-drowning and nearly electrocuted both of which are survivable.

OK help me settle a bet here...

Inspired by the old Ren & Stimpy cartoon where they get electrocuted for peeing on an electric fence, I bet a friend that simply whizzing on an electric fence would NOT electrocute you, since you're not grounded. Yes, pee will probably conduct fairly well, but once a current flow enters your body via the stream, it has no decent outlet since you're insulated from the ground and therefore, completing the circuit. There's also a better "path of least resistance" through the wires of the fence.

My friend disagrees, saying that if one were to pee on an electric fence, you'd get shocked just as Ren & Stimpy did. Obviously we don't want to test this experimentally (at least not admit to it).

What says the Pelican Brain Trust? Any electric fence experts out there?

If you're the type of guy that can piss on overhead wires I'd like to shake your hand!

Well, maybe not since you'd likely also be covered in piss. :)

It's happened to me. Whizzing on a cattle fence in leather soled golf shoes with metal spikes conducts. I can taste the metal in my mouth just thinking about it. It may or may not have helped being a wee bit soggy out. It rained the night before, but the ground wasn't sloppy wet.

So you are telling me that someone that gets pulled from the bottom of a body of water and who has no pulse nor breath is near drowned? I'm curious because my nephew was dead, but is alive.

Anyone seen the video passing around now with the guy in India (or Pak) who stands up on the train and grabs the overhead wire?

There is no doubt that its not faked and he is dead in a mili-second. Falls to the top of the car and burns until the video stops. Its pretty nasty and not for the faint of heart.

OH, THAT is good!

Glad your nephew is still with us!

http://en.wikipedia.org/wiki/Drowning

I googled and found this tidbit at the CDC. I wasn't familiar with the term "non-fatal drowning". But still, the word drown/drowned by itself lends that the person did not survive.

"•Nonfatal drownings can cause brain damage that may result in long-term disabilities including memory problems, learning disabilities, and permanent loss of basic functioning (i.e., permanent vegetative state)."

However, I couldn't find one case of non-fatal electrocution.

Once upon a time, I remember crossing a field in Vermont somewhere. After days of hiking up and down the hills on the Apalachian trail.... in a beautiful grassy clearing across which was a wire with a red ribbon on it.....just lift to get across........zzzzzzzzzzzzzzzz....nope.....not again.
Take that bet and shove it.

Hold on I have it.

Nope, most rail transit runs on 600 volt DC.

john70t 06-17-2009 08:39 PM
It's not not the volts(pressure) that kill, it's the amps(flow).
Look up a Faraday cage or the Tesla static electricity light show, and see a display of human skin being saftely next to many XX,000's of volts.... but just good 1 amp or less across the heart will do a person in.

I've heard higher voltage(like Euro 200V) is actually safer and more efficient.
Touch 220V and the body is bounced off. Touch 110V and the body sticks, and frys...

mattdavis11 06-17-2009 09:04 PM
+1, it's the amperage that kills, not the voltage.

John heard right, it's hard to pull your hand off of the tweezers when you jam it in the wall outlet. That happened when I was 4 or 5, haven't been right since.

An example of what electricity can do: warning...pretty gruesom

DOOOD. Thats what I posted.

You will get zapped peeing on an electric fence absolutely.
Every rural kid got to try's it, or gets dared.I was 9 or 10.
I still shock myself every summer with ours, last time was brushing up against it coming off the tractor I will never pee on one again, thats a one time thing.:eek::eek:

Well, it seems to be an established fact that the current can get to ground even though one is wearing rubber soled shoes, but another variable is the output of the control unit on the fence. Based on what I saw on (I think Wiki) earlier today, there are some fences that could probably kill you because not all fences are pulsed, and some carry a very high voltage.

I'm not familiar with the Ren and Stimpy episode, so I don't know what kind of fence the bet is based on, but I believe what I read said it's not just prison fences that are carrying lethal amperages.
