So we need to rethink how we visualise electricity and the parameters surrounding photons inside a conductor.Can we start that "rethinking" process by realising that the photons are outside the conductor.
You can verify that fairly simply.
The speed of a signal down an insulated cable depends on the refractive index of the insulation.
If you didn't know that, it shows that you don't know what you are talking about...
