# Electrical field lines in conductive wire

Hi

we connect a Voltage to heads of a conductive wire
how will be the field lines inside Wire ? (cylinder wire)

E = $$\rho$$ J

so ? :D

field lines are parrarell inside wire ?

in whole wire Electrical field is constant ?
(J must be more in center of wire)

what about Extreme Conductors ? ( i dont know the word in Eng , those with 0 Resistance)
