The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
Peterson had been an assistant at Brown's July 1888 public electrocution of dogs with AC at Columbia College, an attempt by Brown to prove AC was more deadly than DC. [14] Technical assistance in these demonstrations was provided by Thomas Edison's West Orange laboratory and there grew to be some form of collusion between Edison Electric and Brown.
Tesla then leaves Edison's team. Edison fiercely guards his patents and sues Westinghouse. Edison suggests that AC is dangerous and engages in a publicity war, while Westinghouse stands behind its technical merits. As Edison struggles to find ways to make DC more affordable, Westinghouse attempts to get the high-voltage AC system to work with ...
Edison in 1861. Thomas Edison was born in 1847 in Milan, Ohio, but grew up in Port Huron, Michigan, after the family moved there in 1854. [8] He was the seventh and last child of Samuel Ogden Edison Jr. (1804–1896, born in Marshalltown, Nova Scotia) and Nancy Matthews Elliott (1810–1871, born in Chenango County, New York).
In popular culture, Thompson and Dundy's execution of Topsy has switched attribution, with narratives claiming the film depicts an anti-alternating current demonstration organized by Thomas A. Edison during the war of the currents waged against his competitor, George Westinghouse. This is a popular misconception.
The abbreviations AC and DC are often used to mean simply alternating and direct, respectively, as when they modify current or voltage. [ 1 ] [ 2 ] The usual waveform of alternating current in most electric power circuits is a sine wave , whose positive half-period corresponds with positive direction of the current and vice versa (the full ...

The Westinghouse company installed thirty more AC-lighting systems within a year, and by the end of 1887 it had 68 alternating current power stations compared to 121 DC-based stations Edison had installed over seven years. [19] This competition with Edison led, in the late 1880s, to what became known as the "war of currents". Thomas Edison and ...
