what is a tesla coil
A Tesla coil is a device that uses resonant circuits and alternating current to produce extremely high voltages. Originally invented by Nikola Tesla in the late 1800s, Tesla coils have progressed from spark-gap circuits to designs involving modern solid-state switching devices such as MOSFETs and IGBTs.
