i don't believe the human body is an ohmic material, but i'd be interested to see how much current is running through ya.

Of course the body is ohmic. It has resistance.

Ohmic means it follows Ohm's law, v=IR or j=conductivity dotted with an electric field...

It *has* to follow Ohm's law. There is no other choice about it. Electricity follows Ohm's law, whether the resistance is made of a resistor, a piece of steel, your arm, etc.

Not true, Ohm's law is an observation, many materials do not exhibit Ohm's law, i.e. non-ohmic material.

Example? I'm not farmilar with this.

umm...semi-conductors...lightbulbs...LEDs...

They are non-linear elements (or devices).

All linear devices/circuits follow ohm law.

current is what gets you. grab both ends of a car battery and find out.

A car battery won't do anything at all to you. I've touched the terminals plenty of times working on cars. Your skin has too much resistance for the 12v battery to push any significant amount of current through you.

oh. Duh. I see what you're saying now.

the voltage of the static shock you get when you step out of the car is probably hundreds of times greater than that.

maybe if your hands are wet...but the skin has resistance in the mega-ohm range...

I can EASILY feel the 10VAC of "leakage" voltage we have on Neutral since this house isn't properly grounded.

You cannot feel 10 volts. A car battery is 12 volts and you don't feel anything when you touch that.

and yet a 9V battery touched to a tongue....

Your tongue is wet and doesn't have a thick layer of highly resistive skin on it like you skin does.

So what exactly is the resistance of soy sauce?

4093 ohms.

Um...over what distance?

Specifically, what is the resistivity of soy sauce?

hmm... p = (RA)/l

so about 13.64 ohm meters

good info, now i can sound smart in electrical discussions

your tongue has much less resistance. salty saliva...

gotcha. i still like the people that think that alot of voltage with no amps will kill you. they make my laugh and feel warm inside

this from the one that tried to argue about amount of voltage vs amps

yeah, So made a good point, you couldn't get a good idea about what I was talking about, it could have been a plastic pipe full of soy sauce or a puddle...need to be specific.

oh wait you said 1000 A @ 1 V wouldn't hurt... take a neutral line with no voltage on it that's carrying 1000 amps and put yourself in series with it and then tell me.

i stuck a paperclip into a socket when i was about 8.. i forget if i un wrapped the clip and stuck it in both sockets, or just into one... would it even work if i just stuck it into one? yah, cause i would be the grounding material right? man, i dont' remember this sh!t... but that was something lemmie tell ya

If you would have stuck it in both, you would have blown the breaker...

You guys have it all wrong. Its not the volts, amps, current, or whatever else that has been said that gets you.

Its the electricity.

i hope you are studying that circuit tutorial i sent you... i'll test you soon.:beer:

I did this when I was little with tweezers. Stuck both prongs in both recepticle slots, I got a nice, very warm, very quick buzz, but the breaker blew pretty friggin' quick and it didn't last long. Saw some nice sparks, though . Then I would stick my finger in between the prongs on an appliance plug, and plug it into the recepticle. It sure does warm you up quite a bit! Probably can't do it now, fingers are too big... Ahh the stupid things we do when we're young.

done it, felt nothing

so at 71 you're safe but at 72 you're toast? I'll make sure i mention this on my physics final.

right, cause when you touch the car door and get zapped by 20,000 volts of static electricity, you die right?

lol, i was doing 90 before i left, but i set it to not go over 2 mA, as a safety feature.

so, you put yourself in series with 1000 amps, and are typing from heaven?

I remember one time I was playing around with a 7.2 volt battery pack for my RC car. I was touching the wires together and making sparks. Somehow one of the sparks went into me and shocked the HELL out of me. I don't know how the 7.2 volts go through my skin to send the current through me, but it did.

did you have a cut? or sweaty outside?
