An aluminum transmission line is to be replaced by copper having the same total resistance. If the cross-sectional area of the aluminum wire is 820 MCM, what would be the cross-sectional area of the copper wire? Given: resistivity of aluminum = 17 Q-CM per ft, resistivity of copper = 10.37 Q-CM per ft
