Capacitors
Today I learned about capacitors. A capacitor is a passive two terminal electric component. Capacitors are used to store electrical energy. There are different kinds of capacitors there is the ceramic disc capacitor the poly film capacitor and the electrolytic capacitor. An ideal capacitor is characterized by a single constant value, capacitance, measured in farads. This the ratio of the electric charge on each conductor to the potential difference between them. In October 1745, Ewald Georg Von Kleist of Pomerania Germany found that a charge can be stored by connecting a high voltage electrostatic generator by a wire to a volume of water in a hand held glass jar. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor which was named the Leyden jar after the University of Leyden where he worked. Thank you for reading the way I learned about capacitors was from that video and this site Wikipedia
This video talked about capacitors, the different kinds of capacitors, and how they work. This video told me about what capacitors are made of. The inside of a electrolytic capacitor is wool that is made out long strips of paper and two metal conducters. It also talked about a Leyden jar and how to make your own. Like I said it talked about the different kinds of capacitors there are ceramic capacitors and poly film capacitors and even electrolytic capacitors.

I had no idea capacitors were invented such a long time ago. Thank you for sharing your knowledge.
