PapaYozh:

The '0' in the switchboard is usually earthed. If that man had been standing on a dielectric mat (as he should be, by the way), he wouldn't have gone anywhere. Ask your father if you have a chance.
Ask him if there was a mat - there was a mat, I saw it happen. If you know everything so well, answer what would be the most dangerous thing in a short circuit in an electrical panel where an electrician works (for an electrician).
 
PapaYozh:

A person is killed by a current of 10mA.
too much is enough and two milliamps more than one is already considered dangerous.
 
PapaYozh:


Sorry, that was your phrase about a voltage that kills a person.

It is the electric current that kills a person, not the voltage.

Generally speaking, a voltage of 36V is considered life-threatening, but it is the current flowing through it that kills a person.

clinging to words, you know what I'm talking about .....

It's not AC, it's DC, I think. Direct current is dangerous because it compresses all the muscles and you can't break away from it.
 

By the way here is that post, about the voltage you first mentioned that won't kill )))))

By the way, if you take off the wire from the spark plug when the car is running, you may get electrocuted (and most likely will). The voltage there is about 10kV, but it won't kill you.

Electricity has the following values: frequency, power, voltage and there are tables (you can find them on the internet) which show all these parameters in lethal ratios for humans. Piezo element in a lighter has voltage of 10 kV but it doesn't kill. The video of the corona on the wire also shows very high voltages, but the guy only got his skin burnt, and the stun gun also has very high voltages but mostly does not kill.

So watch what you say too.

 
PapaYozh:
You haven't answered the question: what makes you think that the speed of gravity is faster than the speed of light?


A black hole is a region in space-time whose gravitational attraction is so great that even objects moving at the speed of light (including quanta of light itself) cannot leave it.

There are quantities of electricity like frequency, power, voltage and there are tables (you can search the internet) where all these parameters in lethal proportions for humans. The piezo element in the lighter also has voltages of about 10 kV but it does not kill.

My post was after yours:

Temnyj:
Yes between two, but on each. 220v is a phase and a zero, so the voltage will be 380v, even if you insulate a person from the ground and then hold one wire with both hands, it will be fatal in the vast majority of cases (the exception is different resistance of different people, but it will still be an electric shock), but birds sit quietly with two paws on the wire.
 
Martingeil:

1mA is the minimum tangible current.
 
PapaYozh:

A man is killed by a 10mA current.

Hand held at 150A (cathode in the ion-plasma unit), thus checking if it overheats?
 
Europa:

Did you reach for 150A by hand (cathode in the ion-plasma unit), thus checking if it overheated?


Oh dear!!!!!

What 150 amps? Do you know what the current is?
