His integration of the three properties into a single formula, which became known as Ohm's law, served as a huge stepping stone for all the subsequent advances involving electrical circuits, ranging from electric lights to radios and computers.

Although his parents had not been formally educated, Ohm's father was a respected Ohms law investigation who had educated himself to a high level and gave his sons an excellent education through his own teachings.

Some of Ohm's brothers and sisters died in their childhood and only three, including Georg Simon, survived. The other two survivors were his younger brother Martin who later became a well-known mathematicianand his sister Elizabeth Barbara.

His mother died when he was ten.

Resistors Chapter 2 - Ohm's Law Because the relationship between voltage, current, and resistance in any circuit is so regular, we can reliably control any variable in a circuit simply by controlling the other two. |

They connect ONE wire at a time in a circuit as shown below. The potential difference across each wire is increased in equal increments, and the resulting current through these wires is measured. |

The boys' father taught them from their early childhood, bringing them to a high standard in mathematics, physics, chemistry and philosophy even as he hoped they would follow in his footsteps as a locksmith. Georg Simon attended Erlangen Gymnasium from age 11 to age 15 where he received little in the area of scientific training, which sharply contrasted with the inspired instruction that both the boys had received from their father.

The progress of the Ohm brothers in science and mathematics made them bear a resemblance to the scientifically accomplished Bernoulli family, as noted by the professor at the University of Erlangen, Karl von Langsdorf.

Langsdorf's enthusiasm inspired Ohm's father to relinquish his desire to have the boys take up his trade. Life in university Inat age 15, Ohm entered the University of Erlangen. Rather than concentrate on his studies he spent much time dancing, ice skating, and playing billiards.

Ohm's father, angry that his son was wasting the educational opportunity, sent Ohm to Switzerland where, in Septemberhe took up a post as a mathematics teacher in a school in the Institute of Gottstadt near Nydau, in the canton of Berne.

Karl Christian von Langsdorf left the University of Erlangen in early to take up a post in the University of Heidelberg, and Ohm would have liked to have gone with him to restart his mathematical studies.

For two years he carried out his duties as a tutor while he followed Langsdorf's advice and continued his private study of mathematics. In April he returned to the University of Erlangen. Teaching career His private studies had stood him in good stead, for he earned a doctorate from Erlangen on October 25,and immediately joined the staff as a Privatdocent.

After three semesters Ohm gave up his university post. Inthe Bavarian government offered him a post as a teacher of mathematics and physics at the comparatively poor quality Realschule of Bamberg. Feeling unhappy with his job, Ohm devoted his spare time to writing an elementary book on geometry as a way to prove his true ability.

The school was then closed down in February The work must have impressed the king, because Ohm was subsequently offered a position at a Jesuit gymnasium in Cologne on September 11, Thanks to the school's reputation for science education, Ohm found himself required to teach physics as well as mathematics.

Luckily, the physics lab was well-equipped, so Ohm devoted himself to experiments in physics.

Being the son of a locksmith, Ohm had some practical experience with mechanical equipment. It was here that he developed his theory of the relationship between electromotive force, resistance and electric current.

Inhaving obtained a leave of absence from the gymnasium in Cologne, Ohm arranged for the publication of his theories in Berlin. This work appeared in its most complete form in as a book entitled "The Galvanic Circuit Mathematically Treated.

Ohm's work was misunderstood and poorly received, and Ohm relinquished his position at the gymnasium, becoming practically unemployed until he secured a professorship at the Polytechnic School of Nuremberg in During the intervening years, Ohm did not have access to a laboratory, and his researches came to a virtual halt.

Gradually, however, his explanations regarding the voltaic circuit picked up converts, and his work finally won the admiration of the most illustrious scientists of the time.

In its notice of the award, the society praised Ohm's work. The light which these investigations has thrown on the theory of current electricity is very considerable Had the works of Ohm been earlier known, and their value recognised, the industry of experimentalists would have been better rewarded.

Ohm was elected a foreign member of the Royal Society in He continued teaching, and devoted the remainder of his career to developing a molecular theory of electricity.

He published one volume of the results of his work in under the title, Contributions to Molecular Physics, in which he included an exposition of geometry using a system of oblique-angled coordinates.

In he assumed the post of conservator of the Physical Collection at Munich. This left him little time for research, although he managed to publish a memoir on interference in uniaxal crystals. In he again assumed a teaching post, this time at the high school in Munich. This teaching post inspired him to write a physics text book, which was published in His health, however, was not strong enough to sustain his exertions, and, after a short period of declining health, he suffered an apoplectic attack and died on July 7, The discovery of Ohm's law In his first paper published inOhm examines the decrease in the electromagnetic force produced by a wire as the length of the wire increased.

The paper deduced mathematical relationships based purely on the experimental evidence that Ohm had tabulated.Ohms Law Investigation.
