Hello,
Basically my problem is trying to understand the electric field outside of a current carrying wire. My first thought is that it is zero, but now I am not sure. The boundary condition of the electric field says that the parallel component inside and out must be the same, so this means the the electric field is non-zero just outside the wire. But if that were the case, then some current could go outside the wire right? Help me with my concept here, thanks.
The question is about finding the poyting vector inside and outside of a current carrying wire. I am stuck on the electric field outside the wire.
