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.
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.
The charge on the capacitor discharges as a current through the coil and spark gap. Due to the inductance of the coil when the capacitor voltage reaches zero the current doesn't stop but keeps flowing, charging the capacitor plates with an opposite polarity, until the charge is stored in the capacitor again, on the opposite plates. Then the ...
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.
German physicist Wilhelm Eduard Weber made use of the bifilar coil in his 1848 electrodynamometer. [3] 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]
[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 ...
Shows using the Van de Graaff generator and several Tesla coils are conducted two to three times a day. [26] Many science museums, such as the American Museum of Science and Energy, have small-scale Van de Graaff generators on display, and exploit their static-producing qualities to create "lightning" or make people's hair stand up. Van de ...
