History of Electrical engineering-2

ADISON

the work concerning electrical engineering increased dramatically. In 1882, EDISON switched on the world's first large-scale electrical supply network that provided 110 volts direct current to fifty-nine customers in lower Manhattan. In 1884 SIR PARSONSinvented the steam turbin  which today generates about 80 percent of the electric power in the world using a variety of heat sources. In 1887, TESLA filed a number of patents related to a competing form of power distribution known as alternating current . In the following years a bitter rivalry between Tesla and Edison, known as the war of currents, took place over the preferred method of distribution. AC eventually replaced DC for generation and power distribution, enormously extending the range and improving the safety and efficiency of power distribution.
