Problem 2 A copper wire has radius r = 0.0250 cm, is 3.00 m long, has resistivity p= 1.72-10-8 2 m, and carries a current of 0.400 A. The wire has a charge-carrier density of 8.50 1028 electrons/m³. a) What is the resistance, R, of the wire? b) What is the electric potential difference, AV, across the wire? c) What is the electric field, E, in the wire?
