Mini Tesla Coil Kit 9-12VDC BD243

Tesla coil is a transformer (resonant transformer) that operates on the principle of resonance. It can produce high-temperature and high-pressure plasma, and can ignite, wirelessly transmit electricity, illuminate fluorescent lamps. It has wonderful arcs and used for many fun and very interesting scientific experiments. The primary coil is attached to the PCB board. Assembly required. Input voltage: 9-12V and can be started with 9V battery, but for an arc the working voltage needs to be 12V. PCB board size: 3.1x4cm/1.22x1.57inch
