It takes the output from a 120vAC to several kilovolt transformer & 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. Tesla himself got arcs up to 100,000,000 volts, but I don't think that has been duplicated by anybody else.
Tesla coils are unique in the fact that they create extremely powerful electrical fields. Large coils have been known to wirelessly light up florescent lights up to 50 feet away, and because of the fact that it is an electric field that goes directly into the light and doesn't use the electrodes, even burned-out florescent lights will glow.
he did it for communication advances by transporting power long distances
Tesla used the coil to transport energy without wires but the coil is the basis of anything wireless.
1891
Tesla research in electricity led him to make his coil. In U.S. Patent 0,454,622, System of Electric Lighting (1891 June 23), Tesla described this early disruptive coil.
The tesla coil was invented in 1891 and is still being used today.

In the related links box below, I posted Building A 250,000 Volt Tesla Coil.
In 1891, Tesla invented the Tesla coil, which was widely used in radios and television sets. A Tesla coil is a type of resonant transformer circuit.

Tesla coil is a resonant air core transformer. There are other known devices that are like the Tesla coil.
she discovered how to transmit power wirelessly using a tesla coil. she discovered how to transmit power wirelessly using a tesla coil.
That was the Tesla coil.
