How electricity was invented

How electricity was invented

The question “how electricity was invented” does not sound right, although usually we don’t notice it. Electricity exists independently of us, nobody invented it. Just 600 years BC. er Greek scientist Thales of Milieus drew attention to the property of amber to attract small objects to itself, and Aristotle noted the ability of some eels to defend themselves from enemies by electrical discharges. Thus began the story of acquaintance with electricity and its properties.

Thanks to Galileo Galileo, such a science as physics emerged, one of whose tasks was to understand the interaction and properties of physical bodies. This marked the beginning of research in the field of electricity.

In 1600, the term "electricity" appears. He was suggested by William Gilbert an English naturalist in his work on the study of magnets. Later he came to the conclusion that other materials and substances also have the ability to electrify.

And only in the 18th century, we approach the answer to the question: “how electricity was invented”. First in Germany, Otto von Gerike created the first prototype of an electric light bulb. A little later in England, after conducting a series of experiments, scientist Stefan Gray establishes that some substances have the ability to conduct current.

Next comes the era of intense research. The discoveries follow one another: they talked about different types of electricity, and the first electrical capacitor was created. And twenty years later, after Gray's discovery, the first theory about the nature of electricity sounded. B. Franklin proposed to consider electricity as "intangible fluid" or fluid. The concepts of polarity of charges appear, and at the same time a lightning rod is invented, empirically establishing the electrical nature of lightning.
