I'm going to take a stab at what I've learned. (I promise that as soon as = I have time, I'll get into the math part. But this is documented in the ba= by books so I should be able to do it.) If given a huge amounts of amps that my battery can deliver, when you say o= ne volt may not kill me, but 200 would, then it is the resistance in my bod= y that is the factor. And thus higher voltages overcome resistance more th= an lower voltages. I'm SURE on this list I've been given a mathematical solution to this, so I= 'll figure that one out myself. :-) Lindy -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of= Byron Jeff Sent: Tuesday, October 22, 2013 8:40 PM To: Microcontroller discussion list - Public.
