12V DIY Panel

[SunEagle]

I quote from him earlier today in message

He said
"Volts matters more. 12v 100000 amps is safe to touch

There is a saying that Volts - Jolts and "mills" - Kills. So I would not test your theory that 12v at 10000 amps is safe.

[Guest]

hahaha its not my theory its a friends.

But do you know how much Amps and Volts would hurt you or kill you. And vice versa Volts and Amps.

So like 100Volt and 50amp
or 100 amp and 50Volt

I've never heard "Pushing up daisies"

How about, "going like sixty"? Bruce Roe

The first will definitely kill you. The second could more than hurt you depending on how much resistance is present when your body becomes part of the circuit. If you are standing in water with bare feet and touch that 50 volt 100 amp source it may hurt you or worse.

50 volts and 100 amp going to hurt you

Or can we say 20Volts and 300amps

Or 35V and 100amps

Or 15volts and 30amps

Whats the limit before getting hurt or serious danger

My buddy who is journeyman electrician said anything below 100watts is considered safe

Your buddy, with that attitude, is going to be "pushing up daisys" (dead, buried, underground fertilizing plants) 5W can kill you

Cattle Prods are safe too, but unpleasant. Well below 100W.

It depend on the resistance of the "circuit" (which includes your body, hand, leg, face, etc) from voltage source to ground.

IMO a circuit with any voltage and current above the 10 millamp level is taking a chance you will get shocked or worse.

Do you guys wear insulated gloves when handling solar cells then?

Mike thats too funny. Pushing up daisys quote.
I would of used the term "cooked like chicken"


How could 0,01 amps kill you? how much volts would be necessary for that to happen?

[sdold]

That is because the voltage is above 50 and the amps are high enough to kill you.

That's why I asked about the claim that less than 100 watts is safe. If 12W can kill you, he was either wrong or meant something else.

You wouldn't have 100V and 50A at the same time, or 50V and 100A at the same time. If you mean a 100 volt source that is capable of 50A, or a 50V source that is capable of 100A, the amperage available doesn't matter because your body resistance defines the current, not what the supply is capable of. The current will be around 25 to 50 mA with the 50V supply and 50-100 mA with 100V, based on what I've read about the body having around 1000-2000 ohms resistance. Both can be lethal

Okay Sdold. Thanks for the good information.
