Electrical charges pervade nature, including lightning in a thunderstorm and the signals within our own bodies. Electrical energy also powers many of the devices-refrigerators, televisions, and computers, to name a few-upon which modern life depends. This illuminating volume explores the various aspects of electricity, including electric fields, currents, and circuits, as well as the relationship of electricity and magnetism to the functioning of motors and generators.
