Re: I know it works, but never understood how: Batt/Alt/Start
#1. Electrons in a solid metal flow from neg to pos. I heard/read somewhere that early expermenters going back to Ben Franklin and his kite got the flow direction wrong but the labels stuck.
That said, my other hobby is ham radio, and modern physics has complicated that simple theory. BAsically, it really is magic, with the little elves inside the wires making smoke that carries the current. When the smoke gets out, all the electrons go with it and the device doesn't work anymore. You may have noticed this yourself.
