(a) Estimate the average drift speed of conduction electrons in a copper wire of cross sectional area 1.0×10−7m2 carrying a current of 1.5 A. Assume that each copper atom contributes roughly one conduction electron. The density of copper is 9.0×103kgm−3 and its atomic mass is 63.5u. (b) Compare the drift speed obtained with the speed of propagation of electric field along the conductor, which causes the drift motion.
