A power plant generates 40 MW of AC electricity. This power is to be transmitted to another city via a transmission line that has a resistance of 7.00 (to the city and back). (a) If the lost power along the line is 44 kW, what is the voltage of the transmission line? (b) If the ratio of the number of turns of the transformer's coils is 25, what is the current in the primary coil?
