100mA is already 3.3 times overkill.To do you any harm needs a certaing level of current, from memory 100mA is very likely to kill you.JimB
A 9V battery would not produce a 30mA current through your body. A 9V would very likely produce a 30mA current if you were to shortcircuit it with a piece of wire, but fortunately for us we have much higher electrical resistance than that of copper.But i think 30mA is very small. A 9V battery would produce more. My solar panel produces 0.5A.
The standard threshold for dangerous voltage is about 60V. Below that, no worries.I am just wondering what actually is used to determine the electric shock. We have current, voltage and watt. For example, I have these:
cableA = 1A, 240V, 240watts
cableB = 240A, 1V, 240watts
Which one will shock a person?
Does it depend on voltage, current or watts?
I thought (residential) RCD were set at upto 35mA and 50mA was considered the lethal level.100mA is already 3.3 times overkill.
Safety circuit breakers (detecting current between live and protective earth) are set to the safe side of 15mA.
30mA will kill for sure.

Nope, I would say at 200ma you would be totally fried! Infact, even 30ma is extremely painful, even lethal ... (In my case, it was extremely painful, luckily it only got me through the hand (15kV 30ma neon sign transformer))I was taught that at 70 ma you are in pain and can't let go because you muscles are contracting, at 80 to 90 you get burnt, at 100 to 200 ma your heart goes into ventricular fibrillation and it takes paddles to save your life, CPR won't help, over 200 ma and your heart clamps, once the power is removed, CPR may save your life.

Electric Current Needed to Kill a Human
We've heard many different versions in the past few posts, which only goes to prove that it can vary significantly. But things is correct, 6mA is the accepted figure for causing defibrillation when it flows through the heart, and 30mA hand-to-hand is also a good estimate (you could expect approximately 6mA of this current to flow through the heart rather than taking other paths). It's difficult to provide concrete figures because it depends greatly on the individual physiology and other factors.Nope, I would say at 200ma you would be totally fried!

6ma across the heart is enough to kill ...
It depends on the substance being called plastic.Wow, deadly electricity. Can i touch a 240v/240W/1A wire with a plastic(3 cm squared) which i am holding? If yes, why? Since the plastic is a resistor.
It's current flowing through the cardiac muscle which is dangerous rather than through "the nerves near the heart". Also, I did mention earlier that I was talking about hand-to-hand current, and that the biggest danger will be a proportion of the current passing through the heart.What nobody has mentioned is the path through the body.
Hand to foot is one thing. Most of the current may not reach the nerves near the heart.
Hand to hand, most of the current may indeed affect nerves near the heart. I've always read the path through the body is important. At 100ma all bets are off
