Yeah, it's a combination of the two. Resistance, Voltage and Current I believe are the base terms (I always get mixed up as I'm used to using the components and not in general physics terms.) Ohm's law I believe is what you're looking for. So to find:
-Voltage: multiply current by resistance
-current: voltage divided by resistance
-resistance: voltage divided by current

Code:

V
---
I*R

(I don't know if that'll show up properly)

Anyway, you can easily touch thousands, millions of Volts, it's all dependent on the amount of current (Amps). I can't really remember how to describe it other than the Amps are the real push/punch.

On the topic of what part of electricity kills?

Its a combination of a lot of things that can contribute to death.

1) High voltage in itself will not kill as easily as low because high tends to knock you away where low tends to hold on to you.

2) electricity kills more people that have no ground more so than those with grounds.

3) its amps not voltage that does the most damage.

4) moisture content and whats in the moisture contributes to the effect.

5) people have survived 100,000 volts I think. Isn't that what your average lightening is?

6) Static electricity can kill faster than either AC or DC. I do not remember my physics, but the electricity that makes up static jolts is neither AC or DC.

7) I could be wrong on any or all of these comments but not by much. (I hope)

Thanks UD, I kind of get the general swing of things now.

1) Its a book for crying out load. its not meant to be Satanic, nor is it meant to be religious imo. its a "FANTASY" story

2) God is an awnser for the unknown

i back up my saying with: As soon as science figured it out, the "God" of thunder disappeared didn't he?

3) i dont know what i think on the bible. and that strange thing about the code of the bible thing was interesting. but aload of bs tbh. religion is the belief that the crappy life that person may live is worth it in the end.(in other words they are scared of death and want to belief there is something after death) thats my view on religion.




Yes, My spelling is still terrible!

Pepper, "V" is for electric potential (The unit volt is usually used. However, that is equal to Joule/Coulomb) And V = U/q, which is potential energy divided by charge of the particle. So, using U for electric potential would be confusing :P

From this, you can see that if Voltage is the potential and resistance detracts from the amount of energy output ... then the only thing you're left with is the current (Measured in Ampere).

Power (specifically rate of energy transfer), is measured by potential and current. (P = I*V) Since, 1 W = 1 J/s. This is what is on your electric bill. This, unless you're concerned about touching a live wire, is what you should be concerned with <img src=" SRC="images/smiles/icon_smile.gif">

UD, a lightning bolt is energy ... it can't be alternating or direct ... however, the circuit it's fed into can be either. So, that statement is nonsense, even if it is still true, it's irrelevant. (This is like saying, all Crows are black because I have a piece of white chalk ... and yes, I can explain this argument)



Blame it on Microsoft, God does.

You know, normal people find things they don't know about, but have an opinion on, interesting. But, that doesn't seem to happen with you. You state something and the moment someone disagrees you, you throw derogatory comments at them. Why?

Also, if you would have looked closely I supported one of your bullets. <img src=" SRC="images/smiles/icon_rolleyes.gif">

Crono, doesn't the flow of electrons, from wherever the lightning comes from to wherever it goes, make the current direct?

i know it's the same as saying static electricity has a current when it's name says otherwise, but is it still static when it jumps to ground? or could this jump, and the route it takes, be called a circuit?

You, like so many of the young these days assume I meant it derogatory. If you re-read it and add this bit to it, you might understand better.

I am afraid you might make sense to me, as in... I do not think I am capable of understanding.

Sure that may not make any more sense to you, but some of us reach an age to where we do not really want to know or worse, be reminded how dumb we are.

you 'might" only show me how dumb I am.

Why do you think I put the word "might" in quotations? Could it be to emphasize it so it becomes the focal point of my reply? Now thin for a moment. I do not know exactly how smart/dumb you are, but I know exactly how smart/dumb I am.

So, with this bit of knowledge you know possess, can you ascertain that I was talking about myself and not you?

Shame really. I had to go into detail because you view the world so badly. I just had to have been talking about you.

Well.

It's not that simple <img src=" SRC="images/smiles/icon_smile.gif">

The difference between DC and AC is AC has an oscillating Electro-Magnetic Field. DC doesn't. However. Most of the time, when a type of current is talked about it's in the specifics of a specialized circuit. Like, man made ones.

I haven't read anything on how lightning, a rather pure source of energy (sort of) would pertain to this. I suppose, if it acted like either of these currents ... I guess. But I doubt it would be applicable. Mainly because, unless it is pumped into a circuit it's useless to us.

But, I'm not sure. Never dealt with it specifically. I'm just sure a bolt of lighting, by its self isn't part of either, since it isn't a circuit. However, I would be comfortable saying, once it's made a connection (trying to get to the Earth) that'd it could be DC ... but, again, I haven't studied that far.

I think for most purposes it'd just be considered a source of energy and nothing more. But I could be wrong.

However, this doesn't devalue what I said before, I don't think.

UD, you quoted me and responded directly to what I said, so, unless this is another realm of existence, that means you're replying to me.

Your message came off as arrogant and incredibly condescending. I'm sure if you said that to someone's face they'd get offended as well.

You have to understand the wording you used placed the inadequacies on myself and not you. You started with a seemingly sarcastic comment then went on to imply I couldn't make what I was saying understandable ... not that you wouldn't understand what I'm saying ...

There's a difference and I think that's where the communication breakdown is happening. The way you write a lot of stuff places 'blame' on the person you're responding to and not yourself.

It's not an assumption, but an interpretation.

Actually, I think it jumps from the ground up first. If you look at some photos you can see the traces of (I'm not 100% positive) the -ve charges climbing up to try and meet with the +vely charged clouds.

Yeah, it does that too. But I think he's talking about after a connection is made ... at least ... I'm assuming as much. (You can see it in photos of ... trees specifically, I think)

I never noticed the edit. Sorry, Fishy.

The charge in that case goes down then back up I think. Which is why it's grey-area. It's all buggery, it doesn't go truly AC, but it's not DC either because electrons flow - -> +.

i've never believed that what i do/don't take in is a measure of how smart/stupid i am, just a measure of how interested i am at the time.

once i get to the point that i don't care how the world around me works, then maybe i'll be stupid too.

Yeah. It's a really shady area, because it depends on the actual 'circuit'. Which is anywhere <img src=" SRC="images/smiles/icon_smile.gif">

I read once that lightening can originate in both places. Sky and ground. I also recall something that the ground origins tend to be the bigger of the two in pure power.

Off topic. Does anyone have the science channel on TV?

They had an article about plasma. The experiment took a stick match and lite it. The match was then placed inside a microwave oven. Somehow the flames bursted into balls. The guy on the show said that the theory was that the microwaves converted the flame into plasma similar to ball lightening.

This stuff is leagues above my head, but it was great watching the film of the event.

Anyway, back on topic. I watched lightening hit the ground in a pasture once. I know it hit cause I saw the geyser of molten stuff shoot into the air. (it was night) Next day, I could not locate the spot for nothing. The area simply vanished.

[edit] Crono. It's been a long day. My flight was delayed and I am sleepy as hell right now. I know that there are no cue cards in here, but you will have to take my word. I was talking about myself.
