Nikolai. Tesla.
In 1882, he invented and manufactured the world's first alternator, and created multiphase power transmission technology to design the modern alternating current power system. In 1888, he obtained a patent for the related patent.
He has invented a lot, but for historical reasons, it is difficult to define which of his inventions are his! Because all kinds of trolls are everywhere, so I won't talk about it here, I want to know that I went to see a documentary dedicated to him in the United States. By the way, there is one item that no one sprays, Tesla Company, which produces electric cars, and the engine of the car was invented by Tesla, which no one sprayed haha, because Martin Eberhard named Tesla in honor of the electric engine invented by Tesla (of course, the engine on the car has been optimized and improved again, but the prototype was invented by Tesla).
He was an inventor, a physicist, a mechanical engineer, an electrical engineer. He is considered an important promoter of the commercialization of electricity, and in addition to his achievements in electromagnetism, he is also credited with contributing to various fields such as robotics, ballistics, information science, and nuclear physics.
On the basis of Faraday's discovery of the electromagnetic field theory, Tesla has a number of revolutionary inventions in the field of electromagnetic fields. His numerous patents and theoretical work in electromagnetism are the cornerstones of modern wireless communication and radio.
Michael Faraday, known as the father of electricity, invented the world's first generator, the disc generator. Some say he is the father of alternating current.
However, his generator is only experimental in nature, and it is of little use in real society, mainly a theoretical breakthrough.
So there are also people who say Nikolai. Tesla is the father of alternating current, because the point of Edison's direct current generator was used at the beginning of that era, and the later dispute between direct current and alternating current was the dispute between Edison and Tesla, and Tesla won the victory in the end. So the electricity we use now has been developed little by little since the generator he invented at that time.
Here I will say that many people call all kinds of people the father of alternating current, in fact, many people were manufacturing alternators in Tesla's era, and many people had patents. However, Tesla's generator was the first generator to be widely used and commercialized. Moreover, the multiphase power transmission technology was invented by Tesla, and the modern AC power system was also designed by Tesla, so others can't bypass Tesla.
For example, take the engine as an example, Tesla invented the engine and assembled everything to allow you to drive the car directly, while others in the same period only invented the engine that can start, except that the engine can start, there is no other use, which is not comparable.

......, the father of modern alternating currentThe modern term is generally used relatively rarely, and the generally recognized father of alternating current is Faraday. Because he was the first to discover alternating current and build the first alternating current motor.
And if you ask about modernity, then it should mean someone who has made a significant contribution to modern, practical alternating current technology, after all, Faraday's generator is just a model, a prototype, and almost no practicality. Then I propose two names for your reference:
1, Maxwell. The third greatest physicist in history, the founder of the theory of electromagnetism, four sets of beautiful equations, revealed all the secrets of electromagnetism. Faraday discovered electromagnetic conversion, and Maxwell tells you why and how to convert it.
It can be said that without his theory, all the applications of electricity and magnetism in our modern era would be impossible to achieve.
2, Dobrovolsky. The so-called practical alternating current is the three-phase alternating current we use now. The inventor of the first large-scale three-phase alternating current generator, I think is qualified to compete for the title of the father of modern alternating current.
PS, Tesla's contribution is to make a patent for a 15,000 Hz AC motor and apply for a patent. At the same time, there were dozens of patents. I don't know why downstairs blew him as the father of modern alternating current?

Alternating current is Michael Faraday.
In 1831, Faraday first discovered the phenomenon of electromagnetic induction, which led to the method of generating alternating current, and later generations called him the "father of electricity" and "the father of alternating current".
Michael Faraday Achievement:
1. Michael Faraday was the inventor of the generator and the electric motor.
2. On October 28, 1831, Faraday invented the disc generator, which was the first generator created by man.
3. Faraday puts the magnetic field lines.
and the important concepts of power lines were introduced into physics, opening the way for contemporary nuclear physics by emphasizing not the magnets themselves but the "fields" between them.
4. Faraday Patrick established the concept of "the change of the magnetic field produces the electric field".
5. Faraday discovered the law of electrolysis.
And promote many professional terms, such as anode, yin digging, electrode and ion.

1. The inventor of alternating current is: Nikola Tesla.
2. Nikola Tesla (Nikola Tesla 1856-1943), born in Croatia on July 10, 1856.
is a world-renowned inventor, physicist, mechanical engineer and electrical engineer. In the late 19th and early 20th centuries, he made outstanding contributions to electricity and magnetics.
3. The achievement was in 1882, when he succeeded Edison.
Soon after the invention of direct current (DC), alternating current (AC) was invented, and the world's first alternating current fluid generator was manufactured, and multiphase power transmission technology was created. He is a peerless genius and a great man forgotten by the world, the alternator was invented by him, and he is known as the "father of the alternating current world".
He died of heart failure alone at a New York hotel from the evening of January 5 to 7 at the age of 86, and his patents and theoretical work based on modern alternating current power systems, including multiphase power distribution systems and alternating current generators, helped him usher in the second industrial revolution.

1834 Jacobi, Germany invents the DC engine.
1888 Yugoslav-American Tesla invented the alternating current electric motor.
Nikola Tesla, born 1856 (born 10 July 1856) was one of the world's greatest inventors, physicists, mechanics, rubber dismantlers, and electrical engineers. Of Serbian descent, he was born in Croatia (later incorporated into the Austrian Empire). Tesla is considered an important inventor in history.
He is also well known for his contributions to electricity and magnetism in the late 19th and early 20th centuries. His patents and theoretical forms of work based on modern alternating current electric (AC) systems, including multiphase power distribution systems and AC motors, helped him usher in the Second Industrial Revolution.

1. The father of alternating current is Michael Faraday. He was an English physicist, chemist, inventor, inventor of generators and electric motors. Because of his great contributions to electromagnetism, he is known as the "father of electricity" and "the father of alternating current".
2. Alternating current refers to the current that periodically changes the direction of the current with time, and the current can effectively transmit electricity. But there are actually other waveforms that are used, such as triangular waves, square waves.

1. The father of alternating current is: Faraday.
2. Michael Faraday (September 22, 1791 August 25, 1867), an English physicist, chemist, and famous self-taught scientist, was born in Newington, Surrey, to a poor blacksmith family, and only attended primary school. In 1831, he made a crucial breakthrough in the field of electric power that changed human civilization forever.
3. Michael Faraday was a student and assistant of the famous British chemist David, whose discovery laid the foundation of electromagnetism and was the forerunner of Maxwell. On October 17, 1831, Faraday discovered the phenomenon of electromagnetic induction for the first time, and then obtained a method for generating alternating current. On October 28, 1831, Faraday invented the disc generator, the first generator created by man.
4. Because of his great contributions to electromagnetism, he is known as the "father of electricity" and "the father of alternating current".
Household 220V is alternating current.
1. Direct current: refers to the current that does not change periodically in direction and time, but the current magnitude may not be fixed, and the waveform is generated. Also known as constant current. The circuit through which it passes is called a DC circuit, which is a closed conductive circuit composed of a DC power supply and a resistor. >>>More
Let me tell you a basic common sense, for the human body, the voltage below 36V is safe, when the voltage is higher than 36V, it will cause electric shock. However, the injury caused by electric shock depends on the state of the human body at that time, and the resistance of the human body is not stable. However, according to your question, if the human body is directly connected to the circuit, if there is no other resistor in this circuit, people should finish playing, but there is an exception, there is a resistance in the circuit that connects your human body to a much larger resistance than yours, and it is connected in series with you, you are safe, because as long as the voltage distributed to you is less than 36V, it will be fine.
Because the meter head is a DC meter, a diode turns AC into DC and measures through the meter head. >>>More
