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.
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.
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 the image are 22 feet long.
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 ...
This is a modern unipolar version of the circuit used for entertainment coils, in which one side of the secondary is grounded and the other side is connected to a toroidal-shaped capacitive high voltage terminal. A slightly different form of the circuit, with the positions of the capacitor and spark gap exchanged, is found at Tesla coil 3.svg
