How to make a Tesla Coil (DIY)

Introduction Nikola Tesla invented the Tesla Coil in 1891. We use these coils as high energy electrical transformers. We can use it to produce high-voltage, low-current, high-frequency alternating-current electricity. He used these circuits to conduct innovative experiments in electrical lighting, phosphorescence and X-ray generation. Along with high frequency AC phenomena, we can use Tesla coil for electrotherapy, and the transmission of electrical energy …
