# Electric field strength for a rod vs a wire?

I've found some equations which I should be able to use to calculate the electric field of a uniformly charged rod. What I was wondering was if I could use this to calculate the electric field strength around a wire. I realized that there may be an issue with that because the charged rod is assumed to have a stationary amount of charge while the charge in a wire would be moving. An ampere is one coulomb of charge per second, so for a one meter wire that's conducting one amp of electricity, could I simply convert that to one coulomb per meter and use that as charge density, then calculate the electric field the way I would for a charged rod? I was using this equation for the charged rod.
