Capacitors can prove how incredibly complex even the simplest devices can be in the past few years; capacitor
s are nothing more than an insulator between two conductors, which has become quite complicated in the 250 years of technological development! Almost all of us are familiar with the electrostatic charge generated by friction-this phenomenon is called triboelectricity. When you walk on the carpeted floor, remove the scotch tape from the character, or comb your hair on a dry day, have you noticed that all this leads to the separation of a small amount of positive and negative charges? This static electricity was discovered more than two thousand years ago; however, it was not until the mid-1700s that static electricity was discovered to be a characteristic of energy storage. The earliest discovery of electricity is hard to believe that the concept of capacitors can be traced back to the sixth century BC. The ancient Greeks already knew that amber fragments could attract light particles after being rubbed. The earliest known written record of friction charges dates back to the sixth century BC; when the Greek scientist Thales of Thales noticed such friction. When he rubbed the amber with animal fur, it gained the ability to pick up a small part of the material. Amber becomes charged through the triboelectric effect, that is, the mechanical separation of charges in the dielectric. In fact, amber in Greek is 'electronIn the next 2300 years or so, whenever electric power research was conducted, someone used two different materials and rubbed them together to create separate areas of positive and negative charges. Around 1650 AD, Otto von Guericke built a crude oil electrostatic generator; it was a sulfur ball that was allowed to rotate on an axis. When Guericke grabbed the sulfur ball and quickly turned the shaft, he noticed an electrostatic charge build up. This experiment did not fail to stimulate the development of several forms of friction devices, which have greatly contributed to the study of electricity. Exploration in the eighteenth century AD The eighteenth century is considered to be the age of enlightenment in Europe. This era is characterized by a wealth of knowledge and cultural expansion. Science is a fashionable pursuit, and public conversations on scientific topics have been fully participated by the educated and empowered European class. The most popular are lectures by professionals related to the 'electricity' category. In fact, the term 'electrician' originally referred to individuals who had an understanding of the nature and concept of static electricity. In general, electricity is easily one of the hottest topics in the 18th century, and a lot of exploration has been carried out on electrostatic machines that use friction to generate electric charges. Although friction is a simple and inexpensive way to separate charges that can be used in electrical experiments, the amount of charge generated is too small. Therefore, professionals urgently need some methods to increase the amount of electricity available for experiments. The first outstanding breakthrough The first storage device was discovered by two independent electricians in the winter of 1745 to 1846. One is Ewald Georg Von Kleist, also known as the German scientist Jurgen das Opfa (some people claim he is from Poland), and the other is Pieter Van Musschenbroek, Professor of Mathematics and Physics at Leiden University in the Netherlands, and his device The device manufactured by Von Kleist has a medicine bottle partially filled with water and sealed with a cork stopper. Pass the nail through the cork into the water. By holding the bottle with one hand, make the nail touch the terminal of the electrostatic machine; this helps to get some current. When Von Kleist reached for the nail, in order to remove it from the plug, he noticed that the separated charge could reunite by flowing through his own body. IVan Musschenbroek and his experiment Van Musschenbroek proposed a device almost in the form of a Leyden jar (named after the city), usually called the first capacitor. Van Musschenbroek's equipment and experience are very similar to von Kleist; however, there are three exceptions. One, a visiting student named Andreas Cunaeus, who made a shocking discovery instead of van Musschenbroek. Second, he did make many improvements to the equipment, the most important of which was to remove the water and use metal foil to wrap the inside and outside of the can. Third, he wrote to his colleagues to explain all their information about equipment and experience. In a letter to a colleague, he mentioned not to try this because it was a terrible experience. This sentence makes everyone want to try this because of this simple rule: never say 'never try' something, especially something 'terribleProving that the above statement is 100% true, soon European scientists and a Benjamin Franklin in the United States began to build their own version of an improved charge storage device. On the other hand, Kleist has no detailed records and depth records, so he is often overlooked as a contributor to the evolution of capacitors. However, with the passage of time, both have gained the same credibility, because their research is completely independent, which is just a scientific coincidence. Leyden Jar and its significance Leyden Jar was used to conduct many early power experiments; in addition, its discovery has important significance in power research.
