I have confirmed voltages up to 71 V are safe

[JohnCU]

I stopped at 71 V cause my fingers were both starting to twitch at the ends of the probes...the current was about 1.5mA, the threshold of a tingling, but as you do it more your hands get sweaty (because of nervousness I suppose) so resistance goes down and the current starts going up so...on a good dry day you can probably withstand 70 volts.

They need to take this equipment away from me before I kill myself with it. I already roasted an LED this morning and calculated the resistance of soy sauce.

Wow, oh look, you can withstand high voltages with low current, what a shock(!).

Indeed, the voltage isn't what kills you. Doesn't take much current though... 5 to 10 mA and you are hurting.

You handle much more volts than that with a static shock.

The real test would be getting hit with high amperage.

How much amps would you be getting if you bridged the prongs of a 120v appliance plug while it was plugged in half way? I used to do that when I was little, made the whole right side of my body go numb.

When you kill yourself, would you will me your o-scope?

hook up a car battery to your nipples to spice up your sex life?

About 4-5 mA. That's getting near dangerous. I just tried 80 V and it feel like a prickly finger massage...(?)

Actually, bridging it while it's in half-way would be equally dangerous since the resistances are in parallel, and both the appliance and your finger would be supplied with 120 V.

It's a sourcemeter I use at work, but I will leave it in there for them to donate it for the continued education of ATOT.

Now that you've determined this, here is what I would do: Make a very small cut on each of your middle fingers, just enough to draw a little blood Then wire a couple of probes to the terminals of a 9V battery and touch one probe to each cut. Quite a rush!

<Disclaimer>Do NOT do this, it is bad for your health</disclaimer>

So what exactly is the resistance of soy sauce?

Um...over what distance?

Specifically, what is the resistivity of soy sauce?

hmm... p = (RA)/l

so about 13.64 ohm meters

Could you make a soy sauce circuit? Electrified sushi?
Oh, you could stick LEDs in sushi rolls and light em up

not quite, unless you've voud a way to make well contained soy pockets in sushi rolls.

You can take some probes and connect them from your 120 V outlet into a pickle and it will glow.

I've seen some movies that show otherwise.

70V is nothing. How many volts do you think a lightning strike is? Take one of THOSE and tell us how much it tickles!

 

[scorpmatt]

1A @ 1000V will fry you
1000A @ less than 1V will make you tingle

 

[MrDudeMan]

dude you can take more than 5-10mA before it starts to hurt at all. we shocked ourselves on purpose the first day of my analog circuits lab...your numbers are way too low.

That's hot! Why don't they teach us THAT stuff in all these stupid EE classes!!

shouldnt you be busy getting your family out of financial ruin??

just what the hell are u playing with

I just measured a sharp tingle at 2 mA with a $5,000 meter. Look it up in a book, maybe you had callouses (sp?) on your hand...
