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 ...
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 ...
U.S. patent 390,721 - Dynamo Electric Machine - 1888 October 9 - Relates chiefly to the alternate current machine invented by Tesla; Related to patents numbered US381968 and US382280; Seeks to avoid mechanical drawback of running high frequency machines; Efficient at low speeds; Producing rotating magnetic poles in one element of the machine ...
Tesla is recognized as one of the foremost electrical researchers and inventors. [3] At the time of publication, the book was the "bible" of every electrical engineer practicing the profession. [4] [5] The book contains Forty-three chapters, most of them on different areas of Tesla's research and inventions by Tesla. The first chapter is a ...
Westinghouse's electric business directly competed with Thomas Edison's, who was promoting direct current (DC) electricity. Westinghouse Electric won the contract to showcase its AC system to illuminate the "White City" at the 1893 Columbian Exposition in Chicago. The company went on to install the world's first large-scale, AC power generation ...
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
"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.
