A gold wire (resistivity of 2.44× 10(-8) Ω·m and a temperature coefficient of 3.4×10(-3) °C-1) with a radius of 0.100 mm has a uniform electric field of 2.50 V/m imposed along its entire length. The temperature of the wire is 50.0°C. Assume one free electron per atom. (a) Determine the resistivity of gold at this temperature. (b) What is the current density in the wire? (c) What is the total current in the wire? (e) If brought to the superconducting state, what would be its resistivity?
