GEORG SIMON OHM
Born March 16, 1789, Erlangen, Bavaria
[Germany]—died July 6, 1854, Munich), he was a
notable German physicist who discovered OHMS
law, named after him, which states that current flow
through a wire conductor is directly proportional
(equal to) to the potential difference (voltage) and
inversely proportional (not equal to) to resistance.
Later, the ohm symbol (Ω—Omega is the 24th and
last letter of the Greek alphabet) is adopted as the SI unit of resistance in theoretical electronics and
physics.
Georg came from a Protestant family. Johann
Wolfgang Ohm, his father was a locksmith and
Maria Elizabeth Beck, his mother was the daughter
of a tailor. Although both of his parents had not been properly educated, Johann was a remarkable selfeducated man and was able to give his sons an
excellent education through his own teachings.
In 1805, he entered the University of Erlangen
and received his doctorate degree. Georg wrote
elementary geometry while teaching mathematics at several schools. In 1820, he began experimental
work in a school of physics after he had learned of
the discovery of electromagnetism.
In 1826, Georg would propose laws that helped
explain the results of others working on galvanic
electricity. In 1827, he was able to publish his
famous book called "Die Galvanische Kette
Mathematisch Bearbeitet," that gave his complete
theoretical explanation of electricity. The book talks about the mathematical background necessary for an understanding of the rest of his works emphasizing a non-mathematical approach to physics. Despite Georg several attempts, he was unsuccessful in convincing the older German physicists that his mathematical approach was the right one.
As a result, Ohm's Law" is now the fundamental
law of electrical circuits, namely that "E"
(electromotive force) equals "I" (current) x "R"
(resistance).
E = I x R
Biomeds owe Georg Ohm a gratitude for his
research because the healthcare community most
likely would not have had a definitive way to
perform electrical safety resistance checks, perform
open circuit analysis using a digital ohmmeter, and
we would not have resistors today.
