Homework Statement
If you have an infinitely long straight conductor radius, a,with a current density ρ how do you find the Potential and Electric Field?
Homework Equations
Gauss Law ##\phi = \int{\vec{E}.d\vec{a}} = 4*\pi*q_{enclosed}##
##q_{enclosed}=\int\int\int{\rho dz dy dx}##
##E=-grad(\phi)##
The Attempt at a Solution
I choose the conductor to be along the x-axis. The cross-sectional area is 2*##\pi##*a at a point ##\sqrt{y^2+z^2}## then the integral in x is taken from ##\inf to -\inf##.
