1. Problem statement The current density from the axis in the wire of radius R is given by J = cr3/2 A) draw the current density as a function of r graph B) determine the constant c in terms of Itotal C) determine the current as a function of r. D) draw the graph of the current as a function of r. 2. Known equations 3. Attempt For part a) I think the graph would just look like a gradually increasing graph, since r grows exponentially. For part b) I am just confused on this one, I really don't know just how to start this, I don't know which equation to include to give me c in terms of I Any input is greatly appreciated, thanks!
