Experiments with Alternate Currents of Very High Frequency and Their Application to Methods of Artificial Illumination

Nikola Tesla was a Serbian American‪ inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
Nikola Tesla was one of the most fascinating and gifted scientists and inventors from the end of the nineteenth and the beginning of the twentieth century. Without Tesla's ground-breaking work we'd all be sitting in the dark without even a radio to listen to.
Here is one of Nikola Tesla's most important lectures; it brightened the world and everything in it. Tesla gave this lecture to the London society of electrical engineers on a topic of experiments with alternate currents of high potential and high frequency. Of all these phenomena the most important to study' are the current phenomena, on account of the already extensive and evergrowing use of currents for industrial purposes...
