Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the 20th century. His inventions, patents, and theoretical work formed the basis of modern AC electricity, and contributed to the development of radio and television. Like his competitor Thomas Edison, Tesla was one of America's first celebrity scientists, enjoying the company of New York high society and dazzling the likes of Mark Twain with his electrical demonstrations. An astute self-promoter and gifted showman, he cultivated a public image of the eccentric genius.

In the mid- to late-19th century, a burgeoning science called electricity promised to shine new light on a rousing nation. Inventive and ambitious minds were hard at work. Soon that spark was fanned, and a war was under way to be the first to light - and run - the world with electricity. Thomas Alva Edison, the inventor of direct current (DC), engaged in a brutal battle with Nikola Tesla and George Westinghouse, the inventors of alternating current (AC). There would be no ties in this race - only a winner and a loser - and the prize was a nationwide monopoly in electric current.

Electricity, one of the most common forms of energy, also a basic part of nature. This audiobook introduces electricity, discussing its static and current forms; the uses of batteries, generators, and power stations; and the importance of safety precautions.

For decades, the blasts and howls of the electric guitar have been some of the defining sounds of popular music.
