Georg Simon Ohm :: essays research papers fc
 Georg Simon Ohm      Ã  Ã  Ã  Ã  Ã  At the time Georg Simon Ohm was born not much was known about  electricity, he was out to change this. Georg grew up in Bavaria which is why  most information about Georg is in German. There is even a College named after  him: Georg-Simon-Ohm Fachhochschule Nuernberg. To much dismay not a whole lot  has been written about him. Usually you will find a paragraph of the summary of  his life. I hope to change this flaw in the history books by telling you as  much as I could find on his life.    Ã  Ã  Ã  Ã  Ã  When Georg was growing up his dad, owner of a prosperous locksmith  business, wanted young Georg to study mathematics before joining the family  business. Georg attended a Gymnasium, like a college, in Erlangen, Bavaria (now  Germany) . During his time at this Gymnasium a professor noticed how he  excelled in math. This professor's name was Karl Christian von Langsdorf, Georg  owes this man much credit from his recommendations to others.    Ã  Ã  Ã  Ã  Ã  After he graduated he took a job teaching mathematics at Erlangen  University in 1805. He spent the next years looking for a better teaching  position. He found what he was looking for in 1817 when a job was made  available to him at Cologne Gymnasium. He now looked to research electrical  current. In 1827 he published Die galvanishce Kette, mathematisch bearbeit (The  Galvanic Circuit, Mathematically Treated). This was a mathematical description  of conduction in circuits modeled after Fourier's study of heat conduction.  This is also known as Ohm's Law.    Ã  Ã  Ã  Ã  Ã  Ohm's Law, which is Georg's greatest accomplishment, started as an  experiment. The experiment's purpose was to find the relationship between  current and the length of the wire carrying it. Ohm's results proved that as  the wire increased the current decreased.    Ohm came up with a formula to state these findings. It is V=IR, where  as V=Voltage, I=Current, and R=Resistance. Ohm came up with a statement for  this: current is equal to the tension (potential difference) divided by the  overall resistance. Units of resistance, or ohms, are named after Georg Ohm.  The inverse of resistance is conductance and it's units are mho, or Ohm's name  spelled backwards. This is expressed as G=I/R or I=GV. That is conductance is  equal to Current divided by resistance.    Georg's work was under constant ridicule because it was experiment only  and was irrelevant to a true understanding of nature. So he felt compelled to  resign his job at Cologne. He continued his research after this time. After  six years he got another teaching job at Nuremberg. He was recognized by the  Royal Society of London for his work in the 1840s.
