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.
Nikola Tesla patented the Tesla coil circuit on April 25, 1891. [4] [5] and first publicly demonstrated it May 20, 1891 in his lecture "Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination" before the American Institute of Electrical Engineers at Columbia College, New York.
The facility has several huge Tesla coils on the facility grounds, some of which range over 20 stories in height. Combined these create what the Soviets nicknamed a "lightning machine." Combined these create what the Soviets nicknamed a "lightning machine."
Resonant circuits can generate very high voltages. A tesla coil is a high-Q resonant circuit.. Electrical resonance occurs in an electric circuit at a particular resonant frequency when the impedances or admittances of circuit elements cancel each other.
[11] [12] [13] In 1897 he patented a device [14] called the high-voltage, resonant transformer or "Tesla coil." Transferring electrical energy from the primary coil to the secondary coil by resonant induction, a Tesla coil is capable of producing very high voltages at high frequency. The improved design allowed for the safe production and ...
Electrum or Electrum (for Len Lye) (Len Lye being a New Zealand artist), is a 1998 sculpture by Eric Orr and Greg Leyh built around the world's largest Tesla coil. [1] The coil stands 11.5 meters (37 feet) in height, operates at power levels up to 130,000 watts, and produces 3 million volts on its spherical top terminal. [2]
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.
Henry Leroy Transtrom (1885–1951) was an American inventor and showman who worked with high voltage electricity.His book, Electricity at High Pressures and Frequencies, [1] (1913) is still used as a guide for constructing homemade Tesla coils.
