The point of this problem is to show how slowly electrons travel on average through a thin wire, even for large values of current. A wire made from copper with a cross-section of diameter 0.740 mm carries a current of 13.0 A. Calculate the "areal current density"; in other words, how many electrons per square meter per second flow through this wire? (Enter your answer without units.) The density of copper is 8.99 g/cm3, and its atomic mass is 63.8....
