PES Physics Information Search A Tesla coil is a device that produces a high-frequency, high voltage current. When working at such high frequencies it can generate spectacular lightning-like discharges in to the air. The most popular use for the Tesla coils has been in the film industry, where they are used whenever lightning or electrical arcs are required. Scaled down versions of the tesla coil are also used in television sets. The Tesla coil was …showed first 75 words of 1347 total…

This cycle can be a single pulse, or a series of charge/discharge cycles up to as many as several hundred per second, depending on the current available from the high voltage supply. If the train of charge/discharge cycles is fast enough, the Tesla coil appears to the eye to produce a steady output of electrical discharge, although it is actually a pulsed device.
