A monovalent (one free electron per atom) metal has an atomic volume of 6.34 cc/mol. Compare the thermal velocity with the drift velocity of electrons in this metal wire carrying 7 A at 40 K. The wire has a diameter of 1mm. With the numbers that you’ve calculated, describe the motion of the electrons in a few sentences.

Comment, briefly.) b) If I stretch a given piece of copper wire, making it 0.1% longer, how much would this (roughly) change the resistance from end to end?

Assume that a gold wire 0.32 mm in diameter carries one mobile electron per atom. The mass density and the molecular weight of gold are 1.89×104 kg/m3 and 197.0 g/mol, respectively. Calculate the drift speed of the electrons in this wire when it carries a current of 2.44 A. (ans. 3.28×10-3 m/s)
