Nikola Tesla (/ ˈ n ɪ k ə l ə ˈ t ɛ s l ə /; [1] Serbian Cyrillic: Никола Тесла, [nǐkola têsla]; 10 July 1856 – 7 January 1943) was a Serbian-American [2] [3] engineer, futurist, and inventor. He is known for his contributions to the design of the modern alternating current (AC) electricity supply system. [4]
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 ...
A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.
U.S. patent 487,796 - System of Electrical Transmission of Power - 1892 December 13 - Alternating current generator consisting of independent armature-circuits formed by conductors alternately disposed; Currents developed differ in phase and the field magnet poles in excess of the number of armature-circuits; Motor having independent energizing circuits connected to the armature-circuit of the ...
In 1887, American inventor Charles Schenk Bradley was the first to patent a two-phase AC power transmission with four wires. [citation needed] "Commutatorless" alternating current induction motors seem to have been independently invented by Galileo Ferraris and Nikola Tesla.
"Egg of Columbus" demonstration at the 1893 Columbian Exposition. Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end.

Westinghouse does an AC demonstration at Great Barrington in March 1886. Inventor Nikola Tesla arrives in the United States and begins working with Edison, but is disappointed by Edison's unwillingness to reconsider his ideas and to fulfill what Tesla thought was a financial promise which Edison passes off as just a joke. Tesla then leaves ...
