Re: re: Cables have direction/direction
ok, i may not understand how things really work, but here is my working
model (in my brain).
the propogation of a voltage change is the direct result of the migration
electrons from one molocule to another along the cable. it is the
or scarcity of electrons that defines a positive and negative voltage (in
relation to ground...at the ground state, there is neither an abundance or
scarcity). if this isn't what "voltage" is, then what is it?
