Directionality of wire

Geoffkait 8-13-2017
Even if one wishes to refer to current as the "signal," since current is alternating we only need to worry about the current (signal) when it’s traveling toward the component or, in the case of speaker cables, when the current is traveling toward the speakers. The other half of the time, when the current is traveling in the opposite direction, we can ignore the "signal" since its effects are inaudible.

When "the current" is traveling away from the component in one of the two conductors it is traveling toward the component in the other of the two conductors.

And it is **always** traveling through the input circuit of the component in one direction or the other, aside from the brief instant during each cycle at which the applied voltage crosses zero, and the direction changes.

I would not press this explanation as being supportive of wire (or fuse) directionality.

>>>>That’s precisely my point! That’s why - if wire is directional per se - the cable manufacturer must control the process to ensure that both wires are placed in the cable correctly. You know, since BOTH wires will exhibit directionality. Assuming directionality is real. Which is in fact what manufacturers do, control the process. Hel-loo! Fortunately once you have a process in place the rest is easy. For a fuse it’s even simpler to explain (one can only hope) since there’s only one wire. Thus, you cannot use the example of AC circuits per se to disprove wire or fuse directionality. Please note: I never said this explanation proved or supported wire directionality. What I’m saying is simple but quite different - you cannot use the tired old AC circuits argument to DISPROVE wire directionality. Capish?

What on God's earth makes anyone think that directionality in wire can even be heard in audio signals @ KHz frequencies? If its just pure copper wire- and uniform in make, thickness, etc. across a fixed length, its a conductor, and it will conduct both ways the same- assuming all things are equal in the wire and in the "inputs" (i.e. terminations) on each end of said wire.

Having said that, I have seen scientific evidence where in the Southern Hemisphere that electrons flow in the opposite direction than they flow in the Northern Hemisphere.  Obviously, impacted by proximity to the magnetic poles of the earth.  That said, directionality is possible in the farthest parts of the northern and southern hemispheres, and non-directionality is best observed nearest the equator.  I live in Texas and closer to the equator than many in US, and likely this is the reason I don't see any hints of directionality in my stereo IC's and speaker wiring.

Maybe all the believers should move closer to the equator and all the naysayers should move closet to the poles and just be done with it. 

We can then have an audio UN where disputes can be settled, to no ones satisfaction. 👍 But, at least, we would be content in knowing that in our particular neck of the woods, we'd be right.

All the best,

@nonoise  Very diplomatic of you!  Just please let's not let the UN become involved in audio and screw that up too.  We have a sufficient # of issues as it is.
