# Thread: Highest voltage ever?

1. Hi, I'm just wondering what the highest voltage ever is? I assume it's in lightening bolts? How many volts are we talking? I beleve lightening to be static electricity though, so I'm also wondering what the highest voltage current electricity is? What about the highest amperage?

Do you mean theoretacally or practically (in Earth conditions)?
Theoretically there is no limit to voltage you could have as long as you need
just have sufficient distance between increased charges.You could exchange
charges between Earth and Moon and got godzillion voltages between.
You could exchange charge between one part of the Universe and the other.
As you get to 10 E15 V you may get some quantum effects similar to matter
creation.Positron-electron pair creation.If you mean Earth nature instead then
positive lightning believed to acheve gigavolt potentials.

4. Believe it or not, rubbing your shoes on carpet produces a massive voltage. Much more than the 240V you get out of a socket. The difference is that the current is a lot smaller (the amperes).

Quite strange.Why then 240V is immediately going through you to the ground once you touch it but much
higher voltage is not?

From Pyoko's post:

"The difference is that the current is a lot smaller (the amperes). "

I thought that was pretty clear

Because you are not in contact with the ground. You can touch one of the two 240 v conductors with no harm, if you are not grounded (but don't try it).

8. I have worked as an electrician, and have been shocked several times (and survived, I think).
Usually, the shock caused involuntary muscle contraction and either I flew off of a scaffold(wiring 600v mercury vapor lights for a warehouse), or tools flew out of my hands.

I was shocked by 25000 volts from a transformer once, and it left a strange taste for days, and changed my mild headache into a real pain.

Man made electricity ain't no where near as powerful as that from nature. But we're working on it.

9. I found this story about Germany's renewable energy generation of 22 Gigawatts, don't know if there's ever been more generated though.

10. The lightning on Jupiter is estimated to have a voltage a hundred times greater than the lightning at Earth.

11. Ive seen this clip on youtube once, where a guy would put aluminium foil on his weener, and jam the ends in an electric socket. That was a funny clip... I hope he's still crispy..

12. Let's ask The Borg:

"We are The Borg, resistance is voltage divided by current".

13. You can generate 10's of kV's of voltage by rubbing a fleece shirt with say, fluorescent pipe. You could probably approximate the actual voltage by eye, just assume that air can withstand ~6 kV / millimeter before an electric arc forms (depends on RH% and air pressure).

Lightning voltage is almost unmeasurable afaik, but on Earth it's _at least_ megavolts. Highest voltage used in transmission lines is 800kV to my knowledge. Think it's used in Russia. I don't know about US since I'm European (non-native English speaker too, so sorry for any typos), but at least on West Coast they use at least 500 kV for transmission.

With direct current, even if current is so low that you won't get burns, if you get shocked by over 2-3 kV you may still die after a few days to blood poisoning. This happened couple times in the 90's in Europe with railway mechanics (They use DC in some systems at least in Germany). Of course the fleece shirt example wouldn't produce this high current and I don't have specific numbers, been a while since I studied electric safety

Aaaaand before anyone asks how can a lightning form if air can withstand 6 kV / mm, look up "dynamic electrical field" and think why lightning looks a bit like a "tree", not a direct line
