power These lines transfer energy from the power company to homes and businesses. The energy is transferred at a very high voltage, possibly hundreds of thousands of volts in some cases. The high voltage results in less loss of power due to resistance in the wires, so it is used despite the fact that it makes power lines very dangerous. 17 O U T L I N E CHAPTER Telegraph Colour Library/FPG/Getty Images 17.1...
