What is the current in a wire of radius R = 3.58 mm if the magnitude of the current density is given by (a) Ja = J0r/R and (b) Jb = J0(1 - r/R) in which r is the radial distance and J0 = 5.08 × 10^4 A/m^2? (c) Which function maximizes the current density near the wire’s surface?

Solutions

Expert Solution

The function maximizes the current density can be calcualate using below formula

Where dA=2r.dr

Function (a) maximizes the current density near wires surface since current I=1.363 A maximum.
