Two coaxial cylinders, inner radius a and outer radius b are separated by a material of conductivity given by [itex]\sigma (r) = k/r[/itex] for some constant 'k'. Find the resistance between the cylinders.
Here the conductivity is a function of position and the charge density is not zero in the resistive medium, and the electric field [itex]\vec E[/itex] does not go as 1/r. So how is this problem solved?
