What makes you believe wire to be directional? Wire is able to carry a current because of conduction electrons, which are valence electrons in the atoms making up the wire. They are loosely bound and therefore can move. You can use the pipe analogy. A wire is like a pipe with water in it already (water=conduction electrons). Applying an electric potential difference between the two ends then gives rise to a current. The current is the same regardless of the the direction it's going. It's as simple as that. I am an electrical engineer and so I believe I am qualified to rebuff your statement or wire being directional. Maybe you mean like in a single ended coax configuration that the signal should be applied to the inner conductor and the shield used as return path. If you were to reverse that arrangement, then there might be some noise issues. If that's what you mean, then you're absolutely correct. I am sincerely interested in what makes you believe wire to be directional. It pains me to see folks believe things like this..Sincerely
