Chapter 21, Problem 45P
Textbook Problem

An AC power generator produces 50. A (rms) at 3 600 V. The voltage is stepped up to 1.0 × 105 V by an ideal transformer, and the energy is transmitted through a long-distance power line that has a resistance of 100 Ω. What percentage of the power delivered by the generator is dissipated as heat in the power line?
