An electrical conductor designed to carry large currents has a circular cross section with a diameter of d and a length of L. The resistance between its ends is R.

A) Determine what is the resistivity of the material?

B) If the electric field magnitude in the conductor is E, find what is the total current?

C) If the material has a free-electron density of ne, determine the average drift speed under the conditions of part (B). Use e for the magnitude of the charge on an electron.
