#Number One Weekly #Incredible Inventions: Who Invented the Capacitors Found in Every Appliance? In circuits, capacitors are used extensively, such as DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, and so on.
Each capacitor has two electrodes, which connect two extremely thin pieces of metal, but the two metal sheets are separated by a dielectric, which is all the substances that do not allow the two electrodes to be exposed, such as air, paper, mica sheets, plastics, and so on.
In the simplest word to describe a capacitor, a memory of a static charge. Capacitance is the ability to accommodate charge. The value marked on the capacitor indicates the physical amount of charge that the capacitor can hold.
Speaking of the invention of the capacitor, there are actually two scientists. They independently invented the Leyden jar "Leyton Jar" in different places. The "Leyden tank" is also the prototype of the capacitor.
On November 11, 1745, a priest, judge, and physicist named Pomeranian, now belonging to Germany, was born. Georg von Kleist first invented the "Pomeranian tank". But he did not pay attention to this matter, and wrote to many scholars, many of which he could not accept, and therefore could not reproduce his findings.
The other was the Dutch physicist and mathematician Pieter van Musschenbroek, who also invented the "Leyden Jar" and wrote a letter to the Paris Academy of Sciences on April 20, 1746, which successfully replicated the experiment. In the end, he was named "Leiden Jar" after the University of Leiden in the western Dutch city where he taught.
In 1747, John Bevis, a British physician astronomer, replaced the water in the "Leyden tank" with metal foil, thus constituting the basic structure of modern forms of capacitance, which continues to this day!
So, why is the capacitance represented by the salad? And listen to the next breakdown, pay attention to me to learn more about popular science knowledge.
