How long does the Tesla Coil reach?

Answer 1

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.

Answer 2

A Tesla coil can generate lightning-like electrical discharges that can reach up to several feet in length, depending on the power and construction of the coil. Tesla coils are often used for demonstrations of high-voltage electricity and are known for their impressive visual effects.
