Georg Simon OhmMarch 16, 1787-July 6, 1854

“Its aim is attained if by means of it the variety of facts be

presented as unity to the mind.”

Meet Ohm• German born citizen from Erlangen,

Germany

• Both parents were both very hard working individuals who believed education was the key to success. His father worked as a university locksmith, while his mother grew up as the daughter of a tailor, neither of which grew up with a formal education

• In all Ohm had two other siblings: a sister named Elizabeth Barbera and a brother named Martin, who later became a well known mathematician

• Georg graduated from the University of Erlangen-Nurenberg where he received a doctorate in math

Education and OhmIn 1805 Ohm entered the University of Erlangen but he

became carried away with student life. Rather than concentrate on his studies he spent time dancing, ice skating and playing billiards. Ohm's father, angry that his son was wasting the educational

opportunity that he himself had never been fortunate enough to experience, demanded that Ohm leave the university after three semesters. Soon after Ohm took up some teaching jobs while still keeping

private math studies. Never quite feeling happy, Ohm returned to the University of Erlangen in April 1811 to continue his studies of math. By October 25, 1811 Ohm had received a doctorate in math from Erlangen.

R=V/I or Ohm's LawThe relationship between current(I), voltage(V or E),

and resistance(R). Thus, Ohms Law, which can be stated as, "The current is directly proportional to

the voltage and inversly proportional to the resistance".

R=V/I Ohm found that the current in a circuit varies directly with

the voltage when the resistance is constant. Ohm varied the voltage across the resistance and measured the current through it. In each case, when he divided voltage by the current, the result was

the same.

Awards, Recognitions, Accomplishments

In 1841 the Royal Society in London honored Ohm with the Copley medal, which then

carried the same significance as the Nobel prize does today.

The same year Ohm became a member of the Academia di

Turino, and in 1842 a foreign member of the Royal Society in London. Thus, the eccentric

who used to be seen out walking his dog in the forests on the outskirts of Nuremberg

finally became an internationally recognized and well-known expert. Even has a

crater named after him.

"For his researches into

the laws of electric currents

contained in various memoirs published in Schweiggers Journal,

Poggendorffs Annalen and in a separate work entitled Die galvanische

Kette mathematisch bearbeitet"
