A little bit about the
life and times of Georg Simon Ohm:
Georg Simon Ohm was a German
physicist born in Erlangen, Bavaria, on March 16, 1787.
As a high school teacher, Ohm started his research with
the then recently invented electric cell, invented by
Italian Conte Alessandro Volta.
Using equipment of his own
creation, Ohm determined that the current that flows through
a wire is proportional to its cross sectional area and
inversely proportional to its length. Using the results
of his experiments, Georg Simon Ohm was able to define
the fundamental relationship between voltage, current
These fundamental relationships
are of such great importance, that they represent the
true beginning of electrical circuit analysis. Unfortunately,
when Ohm published his finding in 1827, his ideas were
dismissed by his colleagues.
Ohm was forced to resign from
his high-school teaching position and he lived in poverty
and shame. However, his research efforts gained a lot
of support outside of Germany. In 1849, Georg Simon Ohm
was finally recognized for his efforts by being appointed
as a professor at the University of Munich.
