A Tesla coil is a type of resonant transformer circuit invented by Nikola Tesla around 1891 wich used to produce high voltage, relatively high current, high frequency alternat…ing current electricity. In U.S. Patent 0,454,622, System of Electric Lighting (1891 June 23), Tesla described this early disruptive coil.

About Tesla Coils. With a maniacal grin you flip the switch on the arcade machine and bring it to life. Lightning arcs through the room out of the Tesla coil, the hairs on your body vibrate with a static charge, and for just a moment you feel the sheer power of science coursing through every fiber of your body.

Tesla coils were used comercialy in sparkgap radio transmitters for wireless telegraphy until the 1920s. Today modified Tesla coils are as igniters for high power gas discharge lamps, such as the mercury vapor and sodium types used for street lighting. Tesla coils were used comercialy in sparkgap radio transmitters for wireless telegraphy until the 1920s.

The coil is usually wound into a toroidal (doughnut) shape to allow an even charge distribution around it by avoiding any sharp edges or points. A Tesla coil apparatus is most often used to demonstrate corona discharge and lightning effects at small scale, but may also be used as a type of radio transmitter. It may also be used as a radio receiver circuit. Tesla coils may produce very high voltages in the range of several hundred thousand volts.

How to Make a Tesla Coil. Developed in 1891 by Nikola Tesla, the Tesla coil was created to perform experiments in creating high-voltage electrical discharges. It consists of a power supply, a capacitor and coil transformer set so that voltage peaks alternate between the two, and electrodes set so that sparks jump between them through the air.

Used in applications from particle accelerators to televisions and toys, a Tesla coil can be made from electronics store equipment or from surplus materials. This article describes how to build a spark-gap Tesla coil, which is different from a solid-state Tesla coil and cannot play music.

What is a Tesla Coil? The Tesla Coil is used to produce fantastic high voltage long sparking displays. It takes the output from a 120vAC to a several kilovolt transformer and driver circuit and steps it up to an extremely high voltage. Voltages can get to be well above 1,000,000 volts and are discharged in the form of electrical arcs.

You'll need a power supply transformer, a high-capacitance primary capacitor, a spark gap assembly, a low-inductance primary inductor coil, a high-inductance secondary inductor coil, a low-capacitance secondary capacitor and something to suppress, or choke, the high-frequency noise pulses created when the Tesla coil operates.

(Conversely, to find the spark gap length, multiply the square root of the power in watts by 1.7.) A Tesla coil that creates a spark gap of 60 inches (1.5 meters) would require 1,246 watts.
