Ohm's story

Ohm is a famous German physicist. He discovered the relationship between the voltage in a resistor and the current flowing through it, put forward the famous Ohm's Law, proved the relationship between the resistance of a conductor and its own properties, and also proved the distribution of charge when the current flows stably. In the field of resistance, ohm has made great achievements, and the unit of resistance is named after him. As such a great physicist, Ohm's story is also worth reading.

Ohm was born in an ordinary locksmith's family, and his parents had no formal education, but Ohm's father was very interested in physics and mathematics and taught himself a lot of knowledge, which had a great influence on Ohm. Under the leadership of his father, Ohm gradually became interested in science and showed a talent different from ordinary people. But Ohm's story didn't develop in the best direction. Although he grew up among talented teenagers, Ohm began to spend a lot of time and energy on playing after he entered the university. He often appeared in dance halls, skating rinks and billiards halls, and his angry father sent him to Switzerland, which changed Ohm's life.

It was in Switzerland that Ohm began his real study and research. At that time, the world electric power developed rapidly, and there were many problems to be solved urgently. Ohm studies the law between the current intensity and the number of batteries. In the process of research, an episode happened. Ohm was eager for success and published a paper without verifying the correctness of the conclusion. This behavior has aroused the dissatisfaction of many scientists. And called him an expert. Such a lesson made Ohm do experiments more calmly, summed up in repeated failures, and finally put forward the great Ohm's law.

Ohm's story shows many people that geniuses make mistakes and need to make up for their own shortcomings with efforts.

Ohm's Law

Ohm's law, especially for physicists, is still quite famous today. This law points out that in the same circuit, if the current of a conductor is directly proportional to the voltage across the conductor, then the current is inversely proportional to its resistance, and it is this law that has always had a great influence on it.

Ohm's Law

But people didn't realize the importance of Ohm's law at that time, but with the development of related work and experiments, more and more people began to find that Ohm's law was indeed correct. At this beginning, Ohm's reputation also rose sharply. Therefore, you can see that the expression of resistance in physics is named after this great physicist.

It can be said that the law discovered by Ohm and the formula he developed have brought great convenience to the electrical calculation in physics. If it weren't for his discovery, people might have experienced a lot of ups and downs, and physics might have lost many new discoveries.

In fact, similar to Ohm's discovery, many discoveries in physics appeared in this period, which can be said to be inseparable from the production development and atmosphere at that time, and physicists themselves have a very persistent spirit. Ohm himself has experienced many experiments in the study of current, and it is precisely because of this that everyone is fortunate to see the relevant laws of resistance today.

Ohm's law explains the relationship among current, resistance and voltage. Before this, people never thought it would be like this. Later, this law also showed its amazing power in physical experiments.

Ohm's achievements

At the same time, the research and discovery of resistance and conductance are also ohm's achievements. At that time, in order to study the speculation in his mind, Ohm installed a current torsion balance on a wooden base, and added a glass cover, a dial and a magnifying glass to carry out the experiment. After repeated operations, the relationship between the current size and the current intensity of the conductor is obtained, that is, the formula x=q/(b+l), which shows that the current size of the conductor is directly proportional to the current intensity, and the ohm's achievement is unprecedented.

Referring to Ohm's achievements, in 1826, Ohm also published his own paper, in which he put forward the quantitative expression of Ohm's law and proved that the current intensity in the circuit is directly proportional to the potential difference in the circuit, but inversely proportional to the resistance in the circuit. This is the expression of ohm's law that people are familiar with now.

At the same time, Ohm's own achievements include his ohmic contact, that is, the contact between metal and semiconductor, and point out that the two preconditions formed have great influence on the research of physics at that time and even later. And his own discoveries and achievements have brought great wealth to the history of science.
