A device called the Tesla coil was created by Nikola Tesla towards the end of the 19th century. This type of circuit functions as a resonant transformer and is capable of generating very high voltage, low current, and high frequency alternating current electricity. The Tesla coil is composed of two elements: a primary coil that is connected to a power source and generates a magnetic field, and a secondary coil that is situated close to the primary coil and amplifies the voltage produced by it through resonance.

The high voltage and frequency produced by the Tesla coil can lead to visually stunning electrical phenomena, such as arcs, sparks, and corona discharges. This makes it a popular device for scientific research, entertainment, and education purposes, often displayed at science a basic guide for building a simple Tesla coil using two coils and a MOSFET museums, science fairs, and high-voltage demonstrations.
