The copper wire in a typical residential building has a cross-sectional area of 3.31 x 10-6 m2. If it carries a current of 10.0 A, what is the drift speed of the electrons? Assume that each copper atom contributes one free electron to the current. The density of copper is 8.95 g/cm3, the molar mass is 63.5 g/mole, and 6.02 x 1023 atoms/mole.
