So you think wire conductors in cables are directional? Think again...

Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

Alternating current alternates, it's the energy that flows in one direction.

Those guys in the link above from the OP, when they start talking about digital signal as 0's and 1's, well they pretty lost all their credibility.  Only a layman would think digital as 0 and 1.

Congratulations!  You finally got it.

It's just not true...especially for AC. The AC current travels in both directions. Here's an easy explanation.
Wrong. AC current travels in one direction. Look up Poynting vector. We've been through this. You're a bit late to the party.

The link you provided is like high-school level for those who can't get past first year college.


Watch this animation. The vector moves in one direction. The current does not...hence Alternating Current. Like turning the pedals on a bicycle.

You’re also convoluting the discussion of which direction the current should flow through the conductor...which is also not true. It’s the purity that matters more than the direction it was drawn...which is zero.

Reverse the leads at the speaker and the drivers change direction based on the polarity of the charged magnets. The AC pulses back and forth.
