Georg Simon Ohm: Relationship between V, I and R, Ohm´s life as a teacher


Fremdsprache F a c h w i s s e n L e r n f e l d e r 6 - 1 3 LERNEN KÖNNEN 10/09 Georg Simon Ohm Relationship between V, I and R Georg Simon Ohm, physicist and famous German inventor in the field of electrical engineering, was born in Erlangen on March 16, 1787. As a school teacher Ohm started his research with the recently invented electrochemical cell, the so called Voltaic Pile. Using equipment of his own creation, he found out that the current flow through a wire is proportional to its cross section area and inversely proportional to its length. Later he formulated his findings by stating: The distribution of electromotive force has a definite relationship in connecting resistance, electromotive force and current strength. Thereby he devised the formula So Ohm was able to define the fundamental relationship between voltage V, current I and resistance R in more detail. That discovery is of such importance that it presents the true beginning of electrical circuit analysis. Ohm's life as a teacher He was afraid that the purely experimental basis of his work would undermine the importance of his discovery. He tried to state his law theoretically as clearly as possible, but his mathematically proofs made him an object of ridicule. In the years that followed, Ohm now lived in poverty, tutoring privately in Berlin. He did not receive credit for his findings until he was made director of the Polytechnic School of Nuremberg in 1833. In 1841, the Royal Society in London recognized the significance of his discovery and awards him the Copley medal. In 1849, at last, Ohm's lifelong dream was realized when he was given a professorship of Experimental Physics at the University of Munich. famous berühmt; inventor Erfinder; electrical engineering Elektrotechnik; physicist Physiker; research Forschung; Voltaic Pile Voltaische Säule: erste konstante Spannungssäule, erfunden von Alessandro Volta (1745-1827); equipment Gerät(e), Anlage(n); creation Herstellung, Schaffung; current flow Stromfluss; cross section area Durchmesserquerschnitt; inversely umgekehrt; length Länge; findings Erkenntisse; to state angeben, feststellen; distribution Verteilung; electromotive force elektromotorische Kraft (EMK); relationship Beziehung; voltage Spannung; to connect verbinden; resistance Widerstand; current strength Stromstärke; to devise erarbeiten, ersinnen, entwickeln; formula Formel; discovery Entdeckung; electrical load analysis hier: Theoretische Elektrotechnik; pure(ly) rein; to undermine untergraben; law Gesetz; proofs Beweise; ridicule Spott; poverty Armut; to recognize anerkennen; significance Bedeutung; to award zuerkennen, auszeichnen.
