tesla coil

tesla coil

n.

An air-core transformer that is used as a source of high-frequency power, as for x-ray tubes.

tesla coil

n

(Engineering / Electrical Engineering) a step-up transformer with an air core, used for producing high voltages at high frequencies. The secondary circuit is tuned to resonate with the primary winding

[named after Nikola Tesla (1857-1943), Croatian-born US electrical engineer and inventor]

tesla coil

An electrical device that generates extremely high voltages, usually for the purpose of creating dramatic electric arcs and lightning effects or for producing x-rays. Tesla coils use step-up transformers to boost the voltage of a power supply and build up large charges in a capacitor. A spark gap periodically shorts out the capacitor, releasing its charge in huge current flows, that generate extremely high voltages (up to ten million volts) through an open-air transformer.
