Your skin is fairly resistant, but pierce through the skin and get into that mostly saline solution and the resistance drops significantly and it really does not take much voltage from there. 5v is not a likely killer, but 12v if placed properly could be a problem. I suspect you could find most of the details on the web if you search based on this outline.</span></div><div id="yui_3_16_0_1_1436187848239_490865" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1436187848239_490865" dir="ltr"><span id="yui_3_16_0_1_1436187848239_492746">The short answer on ear lobe to toe for five volts is no not a problem.</span></div><div id="yui_3_16_0_1_1436187848239_490865" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1436187848239_490865" dir="ltr">John Vaughters</div> <br><div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"> <font size="2" face="Arial"> On Thursday, July 9, 2015 11:18 AM, Grawburg via TriEmbed <triembed@triembed.org> wrote:<br> </font> </div> <br><br> <div class="y_msg_container">I know it's always, "it's the current that will kill you, not necessarily the voltage", but surely there is a reasonable way to determine what the "killing" combination is. I've got a book that says 700 mA could do you in if it finds a path through your heart. Is this really suggesting that if I take the 5VDC, 850 mA power supply I use for my Raspberry Pi, hook one lead to my big toe and the other lead to my ear lobe I may end up dead? When we discuss current & voltage in my RPi class next week I'd like some more information to pass on.<br><br><br>Thanks,<br>Brian Grawburg<br><br><br><br><br><br>_______________________________________________<br>Triangle, NC Embedded Computing mailing list<br><a ymailto="mailto:TriEmbed@triembed.org" href="mailto:TriEmbed@triembed.org">TriEmbed@triembed.org</a><br><a href="http://mail.triembed.org/mailman/listinfo/triembed_triembed.org" target="_blank">http://mail.triembed.org/mailman/listinfo/triembed_triembed.org</a><br>TriEmbed web site: <a href="http://triembed.org/" target="_blank">http://TriEmbed.org</a><br><br><br></div> </div> </div> </div></div></body></html>
