Problem 10 (F/Classic Problem): There is a segment of a wire, radius s, length 1. There is a potential difference V across the segment, such that the electric field is axial, uniform, and given by V = El. The resistance of the segment or wire is R. Show that, the Joule Heating in the wire is equal to the Poynting flux into the segment of wire.
