George Simon Ohm
George grew up in Bavaria which
is why most information about George is in German. There is even a
College named after him: George-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.
When George was growing up his dad, owner of a prosperous locksmith
business, wanted young George to study mathematics before joining the
family business. George 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, George owes this man much credit from his
recommendations to others.
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.
Ohm’s Law, which is George’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
George 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.
George’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.
He was awarded the Copley Medal in 1841 and Charles Wheatstone
attributed his work to the findings of Ohm. He became a foreign member
of the Royal Society in 1842. In 1849 Ohm was given his dream job when
he became a professor at Munich. He died 5 years later after
accomplishing his dream.
George Simon Ohm is not a famous man by any means, but his research on
electricity is still in use today. Electricity is very important, so
this makes Ohm an important man even if he is in the shadows. Although
George was the talk of the town in physics, he has somewhat faded into
an unknown. I hope I have enlightened you with a few words of wisdom
about George Simon Ohm.
