Tesla Coils
Mr. Vale showed us how Tesla coils work. He showed us with different rods and also by putting one on top and watching it spin. A Tesla coil is a type of resonant transformer circuit that was invented in 1891 by Nikola Tesla. Telsa coils produce high voltage, low current, and high frequency current electricity. Tesla coils are used in electrical lighting, phosphorescence, e-ray generation, high frequency alternating current phenomena, electrotherapy, and transmission of electrical energy. Before the 1920, the circuits were used in sparkgap radio transmitters for wireless telegraphy. Their main use today is used in entertainment and educational displays. You will find many tesla coils in high-voltage enthusiasts, research institutions, science museums, and independent experimenters.
