Tesla coil

High-voltage resonator

A Tesla coil is an electrical device that produces high-voltage, low-current, high-frequency alternating current.

Invented by Nikola Tesla in 1891, it generates dramatic electrical discharges—long sparks and arcs that leap through the air.

Tesla coils appear in science demonstrations, special effects, and the workshops of electronics hobbyists: The Tesla coil shot purple lightning across the room.
