A power transmission line 50. km long has a total resistance of 0.60 Ω. A generator produces 100. V at 70. A. In order to reduce energy loss due to heating of the transmission line, the voltage is stepped up with a transformer with a turns ratio of 100:1.
(a)   What percentage of the original energy is lost when the transformer is used?
(b)   What percentage of the original energy would be lost if the transformer were not used?
