Homework Statement
Griffiths says in his "Introduction to Electrodynamics" that electric field inside a conductor is 0, but isnide a wire is different from 0. Since wire is also a conductor, how can that be possible? And how to calculate electric field inside a wire? Wire has resistivity [tex]\rho[/tex], radius a and current I trough it.
Homework Equations
E= 0 inside a conductor;
E = [tex]\frac{I\rho}{\pi a^2}[/tex]z (How to calculate this?)
The Attempt at a Solution
Have no idea how to start...
