there is no doubt that Faraday was the first to generate electricity, but if you study the principle of Faraday generator, you will find that it can't be said to be DC or AC, and the direction and magnitude of current depend on the rotating direction and speed of the metal disk. Ideally, it is a DC generator. That is to say, Faraday determined that motion can generate current, but there was no concept of AC or DC.
after that, many people invented and improved generators by using similar principles, but all of them were DC generators.
It was not until Tesla invented the alternator that the concept of alternating current came into being. Generators were divided into alternating current generators and direct current generators. Both of them, represented by Tesla and Edison, started a battle for the market. However, due to many reasons, such as Tesla giving up patent fees, and the better performance of the AC motor invented by Tesla (basically consistent with the alternator structure), AC power has been rapidly popularized.

It can be said that Tesla's generator and motor perfectly combine electricity and magnetism, which is a perfect application and promotion of Faraday's electromagnetic induction principle, and Tesla has thus obtained an exclusive physical unit T. At this point, Tesla's honor is well deserved.
But many things like "Tesla charges for alternating current, and he is the richest man in the world" and "You can't even use your mobile phone without Tesla" are nonsense.
The patent fee is for generators using related technologies, that is to say, each generator should be given a patent fee, but every kilowatt hour generated has no patent relationship with him. Moreover, the patent term is about 2 years, and it is absolutely impossible to become the richest man in the world with a patent.
As for mobile phones, those who have studied electronic technology should know that the functions of CPU, GPU and memory are mainly realized by a large number of logic circuits, and the basic units are diodes and triodes, which have nothing to do with Tesla, but are inextricably related to Tesla's arch-enemy, Edison, because Edison accidentally discovered and applied for a patent when he invented the light bulb. If you are interested, you can look for information. Whether it is diode, triode or logic circuit, the main power supply is direct current provided by battery, and the charger of mobile phone is actually a device that converts alternating current into direct current through rectification, filtering and voltage stabilization. If the power supply is not Tesla's alternating current but Edison's direct current, then a sliding rheostat can be used to charge the mobile phone.
Like the 11 Nobel Prize nominations, it's completely a rumor. Nominations and prizes for Nobel Prizes can be found in official website over the years, so there's nothing to argue about. The same is true of the Tunguska Big Bang, which can be falsified with a little brain analysis.
to sum up, Tesla is indeed the father of alternating current, but it is essentially Faraday's electromagnetic induction principle.
Tesla is a great inventor and a talented engineer in the history of electrical engineering, but he can only be said to be unknown in the field of science. There is no doubt that there is specialization in the technical field. After all, there is no principle equation or formula exclusive to Tesla, and the achievements of other scientists can basically be summarized as a universally established formula or equation, which is the biggest difference.
However, due to some irresponsible programs, media hype, erroneous analysis, hype and conspiracy theories, Tesla's achievements have been greatly exaggerated, which I believe is definitely not what a pragmatic great man expected.
The above discussion is only practical and practical, and it does not belittle or despise anyone. If someone refutes it, I hope I can find the information and evidence first like me with a scientific attitude. There is no basis for accusing Gai of not accepting it.
