A Question about potential difference in Wire

[QUOTE="Baluncore, post: 5921833, member: 447632"] You need to model your wire as an equipotential surface. Any test charge will spread out over the metal surface to effectively charge the capacitance of that surface. It is a mistake to use dynamic ideas to understand stable situations. You need to consider a stable state, or the dynamic transition towards that stable state. The dynamic redistribution of charge in time involves the inductive and capacitive geometry of the circuit. Energy from the battery will begin to be distributed into the electric field when the circuit is first connected. That initial redistribution of charge and the resulting continuous flow of charge through the light globe will distribute energy into the magnetic field. [/QUOTE]
