Hello fellow physics-people,
I was just thinking about the following setup:
We have a conducting surface (with smoothly varying resistivity) hooked up to some battery with the wires contacting the surface at two arbitrary points, A and B. How would we go about figuring out the current density?
Would the electrons flow in a simple curve from point A to B (to follow the path of least resistance) or would they spread out (as there might be a configuration in which parallel flow reduces mutual electric repulsion)?
Any ideas/suggestions? Thanks!
