A Tesla Coil is a type of electrical transformer invented by Nikola Tesla in the late 19th century. It generates high-voltage, low-current, high-frequency alternating current electricity. The device consists of two main parts: a primary coil and a secondary coil, which work together to amplify electrical energy. Tesla Coils are often used in demonstrations of electrical phenomena, producing spectacular arcs of electricity that can jump through the air. They have applications in radio technology, wireless transmission, and even in some medical devices. Their unique ability to create high-voltage discharges makes them a popular subject in science education and entertainment.
