A couple of questions:
When you touch your main AC socket, you’ll get in Europe around 230V @50Hz.
That would be using this calculation 220V/100kOhm = 2,2 mA. Which would only cause a “Tingling sensation”, which simple isn’t true for AC sockets. I know the table and calculations are only for DC circuits, but how do you calculate this for AC?
And statements like these:
“Offhand it would seem that a shock of 10,000 volts would be more deadly than 100 volts. But this is not so! Individuals have been electrocuted by appliances using ordinary house currents of 110 volts and by electrical apparatus in industry using as little as 42 volts direct current. The real measure of shock’s intensity lies in the amount of current (amperes) forced though the body, and not the voltage. ”
But by using the I = U/R calculations and using this table here, 10kV would always be way more dangerous than 42V. How does that work?
