Exercise 46

An AC power generator produces 50 A (rms) at 3 600 V. The voltage is stepped up to 100 000 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 100 V. What percentage of the power delivered by the generator is dissipated as heat in the power line
