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.
[6] [7] [8] Although Tesla patented many similar circuits during this period, this was the first that contained all the elements of the Tesla coil: high voltage primary transformer, capacitor, spark gap, and air core "oscillation transformer". From Tesla's time until the 1930s Tesla coils were widely used in radio transmitters, quack ...
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 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 period is called a cycle). "Alternating current" most commonly refers to power distribution, but a wide range of other applications are technically ...
The two metal sheets are connected to a Tesla coil oscillator, which applies high-voltage radio frequency alternating current. An oscillating electric field between the sheets ionizes the low-pressure gas in the two long Geissler tubes in his hands, causing them to glow in a manner similar to neon tubes .
Large examples were used in inventor Daniel McFarland Cook's 1871 "Electro-Magnetic Battery" [4] and Nikola Tesla's high frequency power experiments at the end of the 1800s. [5] Nikola Tesla patented the Bifilar Coil on January 9, 1894, referring to it as a “Coil for Electro Magnets”.
On January 9, 1943, two days after Nikola Tesla died destitute in a New York City hotel, the FBI called MIT professor and esteemed electrical engineer, John G. Trump, to determine if any of the ...
Later, his transform became a tool in circuit analysis. 1800: Italian physicist Alessandro Volta invented the battery. 1804: Thomas Young: Wave theory of light, Vision and color theory: 1808: Atomic theory by John Dalton: 1816: English inventor Francis Ronalds built the first working electric telegraph. 1820
