Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high-frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in spark-gap radio transmitters for wireless telegraphy until the ...
English: Circuit diagram of a modern unipolar W:Tesla coil, a spark-excited resonant transformer circuit which produces high frequency high voltage alternating current at low current levels. It was invented by Serbian-American inventor Nikola Tesla in 1891.
English: Circuit diagram of a Tesla coil, a spark-excited resonant transformer circuit invented in 1891 by Nikola Tesla.It generates very high voltage, radio frequency alternating current electricity at low current levels.
Free energy proponents claim that Tesla developed a system (the Wardenclyffe Tower) that could generate unlimited energy for free. However, his system was only intended to transmit energy for free; the system's energy would still need to be generated through conventional means. [20]
The "closed primary, open secondary" resonant transformer circuit used by Tesla proved a superior transmitter, [92] because the loosely-coupled transformer partially isolated the oscillating primary circuit from the energy-radiating antenna circuit, reducing the damping, allowing it to produce long "ringing" waves which had a narrower bandwidth.
Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
To progressively feed energy into the primary coil with each cycle, different circuits can be used. One circuit employs a Colpitts oscillator. [38] In Tesla coils an intermittent switching system, a "circuit controller" or "break," is used to inject an impulsive signal into the primary coil; the secondary coil then rings and decays.

Non-inductive bifilar winding Nikola Tesla's flat inductive bifilar coil. A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands.
