Georg ohms biography
Biography
Georg Simon Ohm came from a Protestant family. His father, Johann Wolfgang Ohm, was a locksmith while his mother, Maria Elizabeth Beck, was the daughter of a tailor. Although his parents had not been formally educated, Ohm's father was a rather remarkable man who had educated himself to a high level and was able to give his sons an excellent education through his own teachings. Had Ohm's brothers and sisters all survived he would have been one of a large family but, as was common in those times, several of the children died in their childhood. Of the seven children born to Johann and Maria Ohm only three survived, Georg Simon, his brother Martin who went on to become a well-known mathematician, and his sister Elizabeth Barbara.When they were children, Georg Simon and Martin were taught by their father who brought them to a high standard in mathematics, physics, chemistry and philosophy. This was in stark contrast to their school education. Georg Simon entered Erlangen Gymnasium at the age of eleven but there he received little in the way of scientific training. In fact this formal part of his schooling was uninspired stressing learning by rote and interpreting texts. This contrasted strongly with the inspired instruction that both Georg Simon and Martin received from their father who brought them to a level in mathematics which led the professor at the University of Erlangen, Karl Christian von Langsdorf, to compare them to the Bernoulli family. It is worth stressing again the remarkable achievement of Johann Wolfgang Ohm, an entirely self-taught man, to have been able to give his sons such a fine mathematical and scientific education.
In 1805 Ohm entered the University of Erlangen but he became rather carried away with student life. 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 that he himself had never been fortuna
Georg Ohm
Ohm’s law states that a steady current (I) flowing through a material of a given resistance is directly proportional to the applied voltage (V) and inversely proportional to the resistance (R). The law is commonly expressed as I=V/R. Most, but not all, materials abide by Ohm’s law. Those that do not are usually described as nonohmic conductors. In slightly modified form, Ohm’s law can be extended to alternating current circuits as well as magnetic circuits.
The son of a locksmith, Ohm was born on March 16, 1789 in Erlangen, Bavaria (now part of Germany). He was initially educated by his father, who had considerable knowledge of a variety of subjects despite his lack of a formal education, and later entered the Erlangen Gymnasium. By the time he began studies at the University of Erlangen in 1805, Ohm possessed an excellent understanding of advanced mathematics. Yet he did not dedicate enough time to his education to please his father, preferring to partake in various diversions rather than apply himself to his books. Paternal displeasure resulted in Ohm dropping out of school after three semesters and relocating to Switzerland, where he became a teacher of mathematics.
Though no longer enrolled in a university, Ohm studied the works of important mathematicians during his free time. In 1809 he decided to leave his teaching post to tutor privately, all the while continuing his own studies. Eventually he re-enrolled at the University of Erlangen, receiving a doctorate a year later. Following graduation, Ohm began lecturing at his alma mater. But he was unhappy with the position, which paid poorly, as he would be with most of the teaching posts he held throughout his life. He resigned after a few semesters and accepted another post in Bamberg.
In an attempt to improve his prospects, Ohm penned a geometry textbook and began experimental work that he hoped would lead to publishable treatises. The positive reception of the geometry text led to a
Georg Simon Ohm was a German physicist born in Erlangen, Bavaria, on March 16, 1789. As a high school teacher, Ohm started his research with the recently invented electrochemical cell, invented by Italian Count 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 or Ohm's law. He became professor at the college at Cologne in 1817.
Ohm�s main interest was current electricity, which had recently been advanced by Alessandro Volta�s invention of the battery. Ohm made only a modest living and as a result his experimental equipment was primitive. Despite this, he made his own metal wire, producing a range of thickness and lengths of remarkable consistent quality. The nine years he spent at the Jesuit�s college, he did considerable experimental research on the nature of electric circuits. He took considerable pains to be brutally accurate with every detail of his work. In 1827, he was able to show from his experiments that there was a simple relationship between resistance, current and voltage.
"Ohm the Genius! the Mozart of Electricity ..."
Using the results of his experiments, Georg Simon Ohm was able to define the fundamental relationship between voltage, current, and resistance. 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 until he accepted a position at Nuremberg in 1833 and although this gave him the title of professor, it was still not the university post for which he had strived all his life. In 1852 Ohm became professor of experimental physics in the university of Munich, where he later died.
Ohm�s law stated that the amount o German mathematician and physicist (1789–1854) Georg Simon Ohm (;German:[ˈɡeːɔʁkˈʔoːm]; 16 March 1789 – 6 July 1854) was a German mathematician and physicist. As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relation is known as Ohm's law. Georg Simon Ohm was born into a Protestant family in Erlangen, Brandenburg-Bayreuth (then part of the Holy Roman Empire), son to locksmith Johann Wolfgang Ohm, and Maria Elizabeth Beck, daughter of a tailor in Erlangen. Although his parents had not been formally educated, Ohm's father was a respected man who had educated himself to a high level and was able to give his sons an excellent education through his own teachings. Of the seven children of the family only three survived to adulthood: Georg Simon, his younger brother Martin, who later became a well-known mathematician, and his sister Elizabeth Barbara. His mother died when he was ten. From early childhood, Georg and Martin were taught by their father who brought them to a high standard in mathematics, physics, chemistry and philosophy. Georg Simon attended Erlangen Gymnasium from age eleven to fifteen where he received little in the area of scientific training, which sharply contrasted with the inspired instruction that both Georg and Martin received from their father. This characteristic made the Ohms bear a resemblance to the Bernoulli family, as noted by Karl Christian von Langsdorf, a professor at the University of Erlangen. Georg Ohm's father, concerned that his son was wasting his educational opportunity, sent Ohm to Switzerland. There in September 1806 Ohm accepted Georg Ohm
