Cable burn in

Yes…back to the pure rather than the applied science!

That is tautology.

The electric charge (i.e the electric field) and the magnetic field are the same thing: they are the orthogonal dimensions of the electromagnetic field, macroscopically they are related through transmission of energy (i.e. via the electromotive force - the PD driving the current, or induced my movement within the magnetic field).

…it would make sense that they move to a new point of equilibrium, but not continually along the wire as if they were on a journey.

Well they are moving from the negative terminal to the positive terminal, as long as there is a difference they will keep moving…

…still disagree…they might be thought of as the carriers of the electrical energy and might well vibrate with the energy wave, but they do not progress along the wire. Do the coils in our cartridges oxidise more quickly on account of playing records?

Perhaps this explains it a bit better than i do:

There is a difference between semiconductors (where there is a bandgap) and full conductors (where there isn’t).

The above article covers both

…holes were used to attempt in some way to explain some features of quantum mechanics, more of a human conceptualisation.

It’s still rather simplistic and doesn’t make allowance for the elastic nature of the electromagnetic force.

Yes, but when measured there is a particle and it has a velocity.
Agreed that what’s real on the quantum level, if anything is real, is different

This is Edwin Hall, in case you are interested. Welcome to this thread Edwin!

Are you so sure about the ‘particle’ bit?

…and this sentence includes the one important word!

Am I sure that measurement turns the wave function into a particle? Well, that’s what the Copenhagen Interpretation says. I don’t think any person alive or dead could claim to be sure about quantum physics

IMHO, as long as we talk about “electrons” the concept of particles and velocities applies.
And the question was the movement of electrons and their interaction with the copper. The simplified movement was actually the argument of the “99.999999999 pure” faction.

Agree that in “reality” other things are going on. But then the whole argument that purity helps and that impurities interact with “electrons” is out the window wholesale.

Are we going to discuss quantum mechanics to explain burn-in? This very much exceeds my expectations.

If it’s an electric phenomenon, then it may well be necessary, electricity IS a quantum phenomenon.

Regarding purity, please note that going from 99,95 to 99,9999 is a 0,05% improvement. Too small to interest me, there must be other things.
