[NSRCA-discussion] Max volts

[Phil Spelt]

Turns out, that biological (living) has a fairly 
high internal resistance at initial voltage 
application, but it drops rapidly (resistance 
does) as current flows, such that the longer the 
current flows the lower the internal resistance, 
thus the more current flows for a given 
voltage.  How do I know?  My graduate work 
involved live laboratory animals, and we had to 
know these things for our research.  At one point 
I was rewiring my mentor's laboratory apparatus, 
in when we used capacitive discharge timers.  I 
unplugged everything and was getting shocked 
frequently late one night.  I finally even 
unplugged the radio and wall clock...I learned 
about capacitive discharge from that!! lol (but not at the time!)
