Even 1 milliamp is enough to kill provided the sufficient voltage is there
Sorry Pat, but that is just plain wrong.
Any current below 30 milliamps is barely noticeable.
50 to 75 milliamps is what's called "hold on" current, since this level causes the muscles to lock, usually making the victim hold firmly.
Even at that level, death is rare. It only happens as a result of a heart anomoly.
Most cases of electocution are when there is a high current traveling through a primary organ, causing tissue damage. If you were to apply 600 volts through two points on your tongue, you would probably loose your tongue, but would live, though not to tell about it.
Old electricians used to test lamp sockets by licking their finger, and connecting the live and identified parts. If done right, the socket voltage will cause a current to flow through the saliva, causing it to heat, and allowing a small amount of current to travel along the skin, causing a tingling sensation. Dont try this at home though. If you are well grounded, the path to ground may be through your heart.
