Re: Human electrical resistance
I know thais is way, way off topic but a bunch of you are engineers and Nord's staement just reminded me of something that has always bothered me but I have never gotten a good explanation about. The issue of amps and voltage in basic electronics always confused the heck out of me. V=A/O tells me that 24 volts is not going to deliver a significant amperage through a human being but I understand that in some circumstances it can. Is it basically that I drasticaly overestimate the resistance of the human body? I.e is it that pretty much any old source that is capable of delivering high amperage will drive a boat load through us? And the reason most "high voltage" sources (like the 10,000 V sign transformer I got zapped by as a kid) just can't deliver mcuh in the way of amps so the voltage drops in low load situations? How much resistance does a body have?Nords said:Our photovoltaic panels only generate 24V. But if I didn't treat that with the same paranoia I used to reserve for 440 VAC, the current would launch me across the street like a fried sausage before I realized that I should have disconnected something.
