Speaker cable arrows???

Skin effect isn't worth worrying about in 60htz wiring we aren't talking about microwaves. 

So, you believe the “audio signal” travels inside the conductor, right? Regardless of whether the skin effect applies or not. I’ll ask again, the frequency of what?

While Ralph Morrison is not the last word on electromagnetism, I am not questioning his expertise, because I did read your links (and have one of his books), and there is nothing in them that disagrees with what I wrote Jea48. I am not questioning Ralph Morrison's understanding, I am questioning yours.

Why would I read the other thread you linked to. With the exception of almarg who always writes clearly, it is mainly a miss-mash of misconceptions and partial truths and I have better things that go through it in detail.

How much energy is outside the conductor and how much inside the conductor? If it 80% - 20%? Maybe 50% - 50%? 95% - 5%? If most of the “energy” travels outside the conductor please explain all the heartburn over skin effect, for which very high frequencies travel closer to the surface and lower frequencies travel deeper inside the conductor. Also, frequencies of what? Thanks in advance.

Almost all the energy is outside the conductor. The product of the electric field and magnetic field inside the conductor is near 0, assuming a good conductor. The E-field penetrates the conductor causing charge to move inducing the magnetic field, and with high frequency, that e-field does not penetrate much into the conductor, but in either case, almost all the energy is outside the conductor.

Again, frequency of what? For that matter the energy of what, the “signal.” But what is the signal? Pardon the question. The audio waveform is not traveling down the wire or cable. If not the audio waveform, what else has frequency? Not current, not voltage, not the magnetic field, not the electric field. The alternating frequency? Also, the way I always see the skin effect stated, the “high frequencies” travel nearer to the surface - but not outside the conductor - whereas lower frequencies travel closer to the center of the conductor. Is that completely wrong?

That's the way I have always read it.
