How exactly do conductors conduct electrons?
I'm confident with Maxwell's equations and I can accept a classical treatment like
[tex]\sigma=\frac{nq^2\tau}{m}[/tex]
where [tex]\tau[/tex] is the scattering rate. So actually I'd like to know what exactly happens with the electromagnetic fields when a voltage source is attached.
Where is the field? How does it build up? In the ideal case, conductors don't have a field inside? How to treat that problem here (internal fields,...)? How does the voltage source act microscopically when attached?
