Encyclopedic overview
A Tesla coil is an electrical resonant transformer device designed by inventor Nikola Tesla in 1891. It is used to produce high voltage, low current, high frequency alternating current. Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
Tesla used these devices to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high-frequency alternating current phenomena, electrotherapy, and the wireless transmission of electrical energy. Tesla coil circuits were used commercially in spark-gap transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray devices. Today, their main usage is for entertainment and educational displays, although small coils are still used as leak detectors for high-vacuum systems.
