Tesla Coil

Tesla coil is high voltage technology discovered by Nikola Tesla over 100 years ago. A Tesla coil is a high-voltage air-core resonant transformer. The Tesla coil achieves a great gain in voltage in a very different way than a conventional transformer. Tesla coil's voltage gain is based upon the different impedances of the primary and secondary circuit components.
Tesla coils are extremely dangerous. The entire circuit of a Tesla coil contains deadly levels of voltage and current. A Tesla coil can radiate high voltage sparks many feet out into the air that will strike anything including you. Extreme caution must be exercised whenever operating a Tesla coil. Tesla coils can generate huge amounts of radio frequency interference (should preferably operated only inside a shielded room). Tesla coil operation involves high energy electrical discharge, high voltages, and often high speed rotary gaps. For the beginner, there are plenty of ways to injure or kill yourself. Safety is an important part of fun, successful tesla coiling.
