The current density across a cylindrical conduct radius R

Last updated: 5/29/2023

The current density across a cylindrical conduct radius R varies in magnitude according to the equation wherer is the distance from the central J J 1 5 R axis Thus the current density is a maximum J at that axis r 0 and decreases linearly to zero at the surface r R Calculate the current in terms of J and the conductor s cross sectional area A R
