Hence a perfect conductor would have zero conductance. Zero conductance is in effect infinite resistance. Hence zero resistance gives infinite resistance.
And thencely comes the madness.

Uh huh. Indeed.

These electons also heat the wire due to resistance.

What are you talking about ? Your new electron ?
Conductivity is the inverse of resistance so it will be infinite for a superconductor.

Also there is a limit of how much current you can pass through a super conductor and if you exceed that it becomes a normal conductor same as if the critical temperature is exceeded.

Yes, that's called quenching, or a quench.

(I think no) Does the copper box feel any force? (I think yes). So if the copper box was able to move it would move while the electron inside the box stays still, as it has no forces acting on it.

The electron would repel the electrons of the copper box.  So the inside of the box would have a positive surface charge and the outside would have a negative surface charge.  This results in a force on the electron, attracting it to the box.

In general, charged objects are attracted to neutral objects.

He used the electron just as an indication of an electric field inside the box induced by the two charged external plates. It is a theoretical example where electron is exactly in the middle of the box.
In his example there will be higher density of electrons on the top side of the box than on the bottom side but there will be no electric field inside the box if we ignore/remove that electron from the middle of the box.


Sorry I do not remember if  you express your opinion. Is the electrical energy flowing through wire or outside the wire?
