George Simon Ohm was a German physicist and mathematician who proposed numerous electrical theories. His most famous work is Ohm's Law, which describes the relationship between electric current, voltage, and resistance of a conductor in a circuit.
Biography
Georg Ohm was born on March 16, 1789, to Johann Wolfgang Ohm, a locksmith, and Maria Elizabeth Beck, a seamstress, in Erlangen, Brandenburg-Bayreuth (now Germany).
Despite the fact that his father merely worked as a locksmith, he was able to provide a better education for his children through his own lectures. Georg Ohm had seven siblings, but only three of them survived his childhood: Georg, Martin (a prominent mathematician), and Elizabeth Barbara.
Education
Ohm enrolled at Erlangen University in 1805, but dropped out during the third semester and went on to teach mathematics at the Gott Stadt bei Daud school in Switzerland. In March 1809, Georg Ohm left the school to work as a private tutor in Neuchâtel.
On the encouragement of Karl Christian von Langsdorf, he continued his mathematical studies and returned to the University of Erlangen in April 1811.
Ohm received his degree in mathematics from Erlangen on October 25, 1811, and joined the mathematics faculty. He resigned his work and accepted the offer from the Bavarian government, realizing that he had no prospects and little money.
In January 1813, he was offered a position teaching mathematics and physics in a low-quality school in Bamberg. Ohm also worked as an author of elementary school geometry books, although he was dissatisfied with his work.
The school was abolished in February 1816, and he was assigned to teach mathematics at a crowded school in Bamberg by the Bavarian government. Georg Ohm received an invitation to teach mathematics and physics at the Jesuit Gymnasium in Cologne on September 11, 1817.
He continued conducting numerous experiments there until he moved to Berlin in March 1828 due to a lack of excitement for his job.
Ohm earned a post and a professorship at one of Nuremberg's universities in 1833. The university, on the other hand, was not what he desired to be. The public's awareness and appreciation of Ohm's great efforts came late, and he had to labor hard and for a long time to achieve it.
This was most likely due to his tumultuous relationship with a number of strong figures, including Johannes Schultz, a powerful player in Berlin's education department, and Georg Friedrich Pohl, the city's physics professor.
In 1841, the Royal Society gave Ohm the Copley Medal, and a year later, he joined the Royal Society. Ohm was also chosen to the Berlin and Turin Academies, and he became a full member of the Bavarian Academy in 1845.
Ohm began teaching at the University of Munich in 1849 after accepting a position as curator of the Bavarian Academy in Munich. He attained his objective of becoming chair of physics studies at the University of Munich two years before his death.
The study of the decrease in the electromagnetic force produced by a wire that is extended in size was first published in the scientific publication discovered by Ohm. Based on his experiments, the article establishes a completely mathematical relationship.
Ohm produced two scholarly publications a year later, in 1826, that provided an outline of the conduction circuit model based on Fourier's investigations of heat conduction. He presented a theory to explain galvanic electricity in it as well.
He produced the first steps of a full theory in his second manuscript that year, which contributed to support the release of his famous work on Ohm's law (1827).
When Alessandro Volta discovered a novel electrochemical cell, Omh utilised it in his research to produce Ohm's law. Ohm discovered that the electric current flowing through a wire was proportional to the cross-sectional area and inversely related to the wire length using his own device. In a work titled Die Galvanische Kette, mathematisch bearbeitet, Ohm's law was written.
The discovery of Ohm's law
Ohm's law first appeared in the famous book Die Galvanische Kette, mathematisch bearbeitet (1827) where he gave a complete theory of electricity. In this work, he stated his law for the electromotive force acting between the extremities of any part of a circuit to be the product of the strength of the current, and the resistance of that part of the circuit.
of acoustics Ohm 's law of acoustics, sometimes called acoustic phase law or simply Ohm's law, states that the sound of music is perceived by the ear as a set of a number of constituents of pure harmonic tones. This is also known to be not entirely true.
Georg Simon Ohm died in Munich, Kingdom of Bavaria on July 6, 1854 (age 65), and was buried in Alter Südfriedhof.
Formula and Sound
Ohm 's Law is a statement that the amount of electric current flowing through a conductor is always directly proportional to the potential difference applied to it. A conducting object is said to obey Ohm's law if its resistance value does not depend on the magnitude and polarity of the potential difference applied to it. Although this statement does not always apply to all types of conductors, the term "law" is still used for historical reasons.
Mathematically Ohm's law is expressed by the equation:
V = IR
Where:
I is the electric current flowing in a conductor in Ampere units.
V is the voltage at both ends of the conductor in volts.
R is the value of the electrical resistance (resistance) contained in a conductor in ohms.
