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.
The great inventor Edison recognized Teslas abilities, but because of Tesla's preoccupation with arc light technology, Edison did not want to support Tesla's work in this area. Edison felt that arc lights were old, cumbersome and antiquated. Thus, in 1886 Tesla broke away from his position at the Edison concern and founded the Tesla Electric ...
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.

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.
A coil outside laboratory with the lower end connected to the ground and the upper end free. The lamp is lighted by the current induced in the three turns of wire wound around the lower end of the coil.

Streamer discharges into the air from the high voltage terminal of a large Tesla coil. The streamers form at the end of a pointed rod projecting from the terminal. The high electric field at the pointed end causes the air to ionize there. Video clip of streamers from a Tesla coil.
