Let's say you have a square plate with a voltage applied across two opposite corners, connected by the hypotenuse.(adsbygoogle = window.adsbygoogle || []).push({});

Presumably, the electric current density distribution throughout the plate would be such that it would follow the path of minimal resistance, i.e. through the hypotenuse.

If you had a way of measuring the current density at a point in the plate (e.g. IR thermography) would the readings show that the current density has a spatial distribution throughout the plate and indeed even a change through the thickness?

What factors determine how the charge carriers are distributed in a conductive medium?
