the guy Posted January 22, 2010 Share Posted January 22, 2010 how many watts is deadly to a human? Link to comment Share on other sites More sharing options...
insane_alien Posted January 22, 2010 Share Posted January 22, 2010 by which method? because it can be done with microwatts by some and gigawatts by others. Link to comment Share on other sites More sharing options...
Phi for All Posted January 22, 2010 Share Posted January 22, 2010 It's the amps that kill, and it wouldn't take much if it went directly through your heart. Link to comment Share on other sites More sharing options...
insane_alien Posted January 22, 2010 Share Posted January 22, 2010 about 12 microamps through the heart will kill. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted January 22, 2010 Share Posted January 22, 2010 You still need a voltage for the current to actually flow, and it has to be done fast enough, so it does take a minimum of power to kill. Of course, if you increase the voltage and decrease the amps you can pass more energy through you but not kill you, so in that sense watts hardly matters.

John Cuthber Posted January 23, 2010 Share Posted January 23, 2010 I suspect it's a matter of Joules that can kill, rather than Watts. Link to comment Share on other sites More sharing options...
uncool Posted January 23, 2010 Share Posted January 23, 2010 I suspect it's a matter of Joules that can kill, rather than Watts. I doubt that it is either, because with Watts you can make it happen for as short as you want, while with Joules you can extend the power out over a lifetime. I'm sure that in your lifetime you easily absorb more than a Joule in electric power. =Uncool- Link to comment Share on other sites More sharing options...
rogerxd45 Posted January 23, 2010 Share Posted January 23, 2010 i always heard about 6 milliamps directly to the heart can do it. but your skin has some resistance so it depends whats on your skin, where it enters and exits. there is no answer to this question but the main thing is stay away from high amp things. high voltage can carry more amps but low volts doesnt make it safe just make sure the electricity has a better path then you! electricity will always take the path of least resistance so just make sure thats not you Link to comment Share on other sites More sharing options...
