Answer:

Explanation:

The current density across a cylindrical conductor of radius R varies in magnitude according to the equation J=J0(1−Rr) where r is the distance from the central axis. Thus, the current density is a maximum J0 at that axis (r=0) and decreases linearly to zero at the surface (r=R).
