A straight cylindrical wire lying along the x-axis has a length of 0.500 meter and a diameter of 0.20 millimeter. It is made of material that obeys Ohm's Law with a resistivity of p = 4.00 x 10-8 Ω•m. Suppose that a potential difference of 4 Volt is maintained at x = 0, and that V = 0 at x = 0.500 meter?

(a) Determine the electric field in the wire?

(b) Determine the resistance of the wire?

(c) Determine the electric current in the wire?

(d) Determine the current density in the wire.

(e) If the conduction-electron density for the material is 8.5 x 1028 electrons/m3, determine the drift speed.
