Directional wires/cables


Is there any reason to support the idea that cables, interconnects or any other kind of wiring can be considered directional? It seems that the theory is that carrying current will alter the molecular structure of the wire. I can't find anything that supports this other than in the case of extreme temperature variation. Cryo seems to be a common treatment for wire nowadays. Extreme heat would do something as well, just nothing favorable. No idea if cryo treatment works but who knows. Back to the question, can using the wires in one direction or another actually affect it's performance? Thanks for any thoughts. I do abide by the arrows when I have them. I "mostly" follow directions but I have pondered over this one every time I hook up  a pair.

Wow, all this technobabble is giving me a splitting headache.  I received my EE in 1976.  Wire directions never came up in any of our studies. Perhaps it wasn’t known at the time?  The school, Roger Williams University had an excellent Electrical Engineering program.  Like I said in the second or third post to this thread, if there are not any arrows on the cable, try it both ways and if you hear a difference to the better, put the cables that way.  Easy Peezy. 

@jea48 -

S represents the signal. Yes?

                                                        wink

     The 'S' stands for Sinousoidal electric field, which when combined with it's magnetic field, results in the Poynting vector that determines the direction and strength of the electromagnetic wave's energy* flow.

                                 *our systems' AC or musical signals

                                         SO, basically: yeah!

                                             Happy listening!

Does the green arrows represent the signal traveling from the source to the load through the dielectric insulation?

Is the EM wave the signal, or does the EM carry the signal? Or is the signal embedded in the EM wave?

I would really like to nail this thing down.

@stereo5 

Were you taught the signal travels in the wire or travels in the spaces between the wires?
