Transcript of "The leyden jar"

  1. 1. THE LEYDEN JAR
  2. 2. PresentationGood morning to everybody, we are threeHaig school students doing a technologicalprocesses.The members of the group are: Gerard,Ariadna and Oriol.Now we are going to talk about our projectOur project is: THE LEYDEN JAR
  3. 3. DEFINITIONThe Leyden jar is a capacitor and anelectronic device that is used to storeelectrical energy. They are only usedto store the electrons and they arenot capable of producingthem.
  4. 4. INVENTION OF THE CAPACITOR Ewald Georg von KleistThere are many stories behind the invention of thecapacitor. A German scientist named Ewald Georg vonKleist was known to invent the capacitor in November1745. But, he did not have any detailed notes or recordsof his invention. So, he was given the credit for evolutionof the capacitor. Ewald Georg von Kleist
  5. 5. PIETER VAN MUSSCHENBROEKA few months later a Dutch professor called Pietervan Musschenbroek found a similar device calledthe Leyden Jar. Scientists approved this to be thefirst capacitor. After years, both the scientists havebeen given equal credit for the invention of thecapacitor.Pieter Van Musschenbroek
  6. 6. Benjamin FranklinYears later, Benjamin Franklin experimented with the LeydenJar, and was able to make a smaller capacitor which wasnamed as Franklin Square after him. Later English chemistMichael Faraday began experimenting on the Leyden Jar,and invented the first commercial capacitor. This capacitorwas made from large oil barrels. This was later progressed insuch a way that electric power could be delivered to verylarge distances. Benjamin Franklin Michael Faraday
  7. 7. THE LAYDEN JARThe Leyden Jar basically consists of a glass jar, which was linedinside and outside with metal foils usually made of lead. The glassjar was half filled with water. The glass jar was used as thedielectric. A brass rod is introduced from the top of the glass jar. Astatic supply was then given from the brass rod into the jar.When this is delivered the jar will store two equal,but opposite charges in equilibrium which passes on to the ground if a ground wire is given. The figure of a Leyden Jar is given below.
  8. 8. WORING OF A CAPACITOR A capacitor is defined by the type of dielectricselected. It also defines the application of thecapacitor. According to the size and type of dielectricused, the capacitor can be used for high-voltage aswell as low-voltage applications. For applications inradio tuning circuits air is commonly used as thedielectric. Take a look at the figure given below toknow about dielectric in a capacitor:
