It's three things. Amps, voltage and resistance. i.e. ohms law. Amps (current) is proportional to voltage and inversely proportional to resistance.
It takes about 100 ma or so to kill. If my memory serves me correctly.
I = V/R

Shocking!
0.25 amps will kill most humans.
The biggest danger of hybrids is that most of the people driving them are retarded.
No. The electric motor has to draw hundreds of amps at startup. A human touching 300 volts will only draw milliamps, due to the internal resistance of the human.
It's not the voltage that kills, it is amperage through the heart that kills, and that only requires about 100 milliamps. The amount of voltage required in order to get that 100 milliamps varies with how well you are connected to the circuit, how much resistance there is, how much body tissue is between the two contacts, and what you're made of.
Defibrillator paddles are placed right on the chest, coated with conductive grease (you've seen it in the movies, I'm sure) and they are designed to up the voltage until the desired amperage is obtained for the desired length.
If you grab the positive terminal with one hand, and the negative terminal with the other hand, I doubt that 300 volts would kill you, but I wouldn't try it.
On the other hand, I've had spark plug wires bite me many times, and that's 10,000 volts and up. Very low amperage, however. Same with those "novelty" packs of gum that give you a shock when you grab them. High voltage, low ability to deliver amperage.
How ironic, I just had a safety meeting at work pertaining to arc flash and static electricity. The supervisor was humming about the rubber gloves and the leather protectors. Every time I open a panel with 50 volts or more I need my proper PPE, no excuses. No more troubleshooting machines live without my gloves,glasses,cotton shirts and caution tape 48” away blocking the common folks.
But Al Gore says we should count all the volts.
We have a winner!
LOL, brilliant!
It seems to me that the whole popularity of hybrids arises from ignorance and rigid thinking. The correct solution is the small turbo diesels pioneered by the Europeans, the French and the Germans (VW Jetta TDI anyone?). These powerplants are really tiny, between 1.0 and 2.0 liter displacement, have *really* great mileage, are peppy, and relatively clean burning.
Much of the fault is with both General Motors, and the Japanese. General Motors, perhaps on purpose, gave the diesel powered automobile a permanent black eye in the United States with the horrid diesel they offered in the mid seventies. With all the money spend on useless Auto show stylist exercises, they could have easily designed a fantastic small diesel, much better than the French could.
But they didn't. May GM live in bankruptcy hell.
I also blame the Japanese, who could have started designing a really efficient diesel but didn't because of the black eye diesels have in the US - and all Japan *really* cares about is the US market. The KOREANS saw the lack of interest the Japanese had in diesels, and jumped into the breech: Hyundai for example builds a really excellent 1.6 Liter CRDI that greats great mileage (for sale outside the US at least - Toyota, Honda and Nissan have *nothing* similar in this size).
The hybrid is an overengineered, overcomplex solution to a problem that has more a far simpler and more elegant answer, the small displacement turbo-diesel.
“You can take a 100000 volts without a problem...”
Err, no thanks I’ll take your word for it.
Some people just don’t think that a smoke test is safe.
Thank you. I dread these threads with people spouting nonsense.
As if "It's not the speed of the water in the stream that drowns ya, it's the width of the river!"
True. Wait until the "greenies" figure out all of the environmental issues in disposl of the batteries.
Very few people ever bother to consider the consequences of alternative energy whether it's hybrid, electic (GM's Volt), "bio" ...

I found it on DVD several months ago. Always has been my favorite buddy-cop movie. :)

That was a great film.
Considering the minimal mileage difference and the increased cost of the Hybrid, The owner would have had to drive over 300,000 miles to break even, assuming the batteries didn't have to be replaced.
Personally, I think it's sunset for the Hybrids. The gleam is off, and people are starting to evaluate them as vehicles, not fashion statements. As a fashion statement, they're like Crocs. They're so ugly some people think they're cool. As vehicles, they suck.
Excellent.
“It’s not the volts, it’s the amps if I remember correctly.”
It is - you do.
I love this thread.
