In my penultimate building electrical class, on the first day of school, I was about to start talking about the history of electricity, when a student asked me the following question: – Teacher, who invented electricity?
Faced with this question many things came to my head and one of them the next, how can so much naivety? But then I thought: How many people know the history of this natural phenomenon that we use all the time, it brings us so much comfort and possibilities and at the same time we barely notice?
One of the first human contacts with electricity was in a phenomenon that revealed two things to the human being, fire and electricity, when still in prehistory a lightning bolt cut through the sky, strong noise and a very bright and instant light started a fire in a forest, this was the moment when the cavemen discovered fire and electricity (although on that occasion they used only fire and had no idea that it was pure electricity).
Tales of Miletus (Sec. VI BC) many millennia later he was the first scientist to be concerned with studying the phenomenon of electricity. He discovered by chance that an amber stone that he probably kept in the pocket of his garment, made from the skin of some animal, was curiously attracting small lint and small grains. The rubbing of amber to the garment was electrifying amber. The Greek word amber is Electron and from this word, the term electricity came.

There were many scientists who, after Tales, studied electricity and each one of them brought their contribution to the evolution of electricity. W. Gilbert was the one who, two thousand years after Tales, began systematic studies on friction and the attraction that amber had on other bodies, initiating what was later called electrostatics. It was Gilbert who started the study on the resistance that certain materials exerted in being electrified, giving the basis for the beginning of studies on the electrical resistance of materials.
Big names are remembered over the decades when we talk about electricity, names like Alessandro Volta, André-Marie Ampère, Georg Simon Ohm, Thomas Edison, Nicola Tesla, Michael Faraday, Benjamin Franklin. Franklin was the one who discovered that lightning (lightning strikes) were natural phenomena of an electrical nature. a metallic structure in order to “attract the rays”, because otherwise, this experiment could have been fatal.
