What is the current in amperes in a wire of radius R = 4.59 mm ifthe magnitude of the current density is given by (a) Ja = Jr/R and(b) Jb = J(1 - r/R) in which r is the radial distance and J = 7.52x 104 A/m2?
I guess you have to calculate the current with integration and usea function for the infinitesimal area dA. I'm not sure how to dothat.
