Question:
A potential difference V drives a steady current I through an ohmic wire with conductivity σ and a constant circular cross section. One portion of the wire has the shape of a circular arc with inner radius of curvature R1 and outer radius of curvature R2. Find the dependence of the current density j on the local radius of curvature r defined in the diagram.
