what is the power lost by a transmission line (made of Al) carrying 10 kA of current? The line is 2km long and the diameter of the wire is 2cm (Hint: take care with your units here, give your answer in W) By what percentage would the power loss change if the transmission line was switched to Cu? Would the resistance of the line increase of decrease?
