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.
To fix this problem Tesla came up with his "oscillating transformer", with an air gap instead of insulating material between the primary and secondary windings and an iron core that could be moved to different positions in or out of the coil. [98] Later called the Tesla coil, it would be used to produce high-voltage, low-current, high frequency ...
The Tesla Wardenclyffe Project, Inc. was established in 1994 for the purpose of seeking placement of the Wardenclyffe laboratory-office building and the Tesla tower foundation on both the New York State and NRHP. Its mission is the preservation and adaptive reuse of Wardenclyffe, the century-old laboratory of electrical pioneer Nikola Tesla ...
During 1899-1900 Tesla built this laboratory and researched wireless transmission of electric power there. The Magnifying Transmitter, one of the largest Tesla coils ever built, with input power of 300 kW could produce potentials of around 12 million volts at a frequency of about 150 kHz, creating 130 ft. (41 m) "lightning bolts". The arcs in ...
Tesla coils were also used as dramatic props in early mystery and science fiction motion pictures, starting in the silent era. [32] The crackling, writhing sparks emanating from the electrode of a giant Tesla coil became Hollywood's iconic symbol of the "mad scientist's" lab, recognized throughout the world. [138]
In air at sea level pressure of 101 kPa, the critical value is roughly 30 kV/cm, [1] but this decreases with pressure, therefore, corona discharge is more of a problem at high altitudes. [4] Corona discharge usually forms at highly curved regions on electrodes, such as sharp corners, projecting points, edges of metal surfaces, or small diameter ...
Electric discharge showing the lightning-like plasma filaments from a Tesla coil. (Click image for detail) Demonstrates several phenomena, looks good at high resolution Nominate and support. - Iantresman 22:28, 29 May 2006 (UTC) Comment Interesting image, but the background is awful. ~MDD 46 96 01:47, 30 May 2006 (UTC)
With the success of Tesla's A.C. system, it soon became the preferred method of generating electricity worldwide. Tesla worked on a number of other inventions, including a transformer that would change a low voltage to a high voltage by means of safe A.C. electric current. This transformer came to be known as the Tesla coil.
