A copper wire has a circular cross section with a radius of 1 mm and length of 1 m. The resistivity of copper at room temperature is 1.68 x 10 m. (a) [2 points] Determine the resistance of the wire. (b) [2 points] if there is a difference of 10V between the ends of the wire, determine the current through it. (c) [2 points] Determine the current density in the wire. (d) [2 points] Determine the magnitude of the electric field in the wire.
