交流电（Alternating current）

共查到三家，意见不同。

第一家，中文，知乎。

交流电是迈克尔·法拉第发明的，他是一名自学成才的科学家，在1831年的时候，法拉第首次发现了电磁感应的现象，从而得到产生交流电的方法，后人称他为“电学之父”和“交流电之父”。
迈克尔·法拉第成就：
1、迈克尔·法拉第是发电机和电动机的发明者。
2、在1831年10月28日，法拉第发明了圆盘发电机，这是人类创造出的第一个发电机。
3、法拉第把磁力线和电力线的重要概念引入物理学，通过强调不是磁铁本身而是它们之间的“场”，为当代物理学开拓了道路。
4、法拉第向人们建立起“磁场的改变产生电场”的观念。

Alternating current power drives our world today. AC power was the next logical step after DC power was established. The founders, developers, and visionaries of AC power are depicted below.

注：爱迪生和特斯拉之间，矛盾极大。1912年,由于特斯拉和爱迪生在电力方面的贡献,两人被同时授予诺贝尔物理学奖,但是两人都拒绝领奖,理由是无法忍受和对方一起分享这一荣誉。

History of Alternating Current, Discovery and Distribution

https://solar-energy.technology/electricity/electric-current/alternating-current/history

In the industrial origins of electricity use, the electrical system used in the nineteenth century was direct current. However, with the arrival of alternating current by the scientist Nikola Tesla the world was revolutionized again.

 Who Discovered the Electromotive Force?

It was discovered by the British Michael Faraday in 1831. Faraday noticed that a conductor rotating in parallel within a magnetic field generates a constant electronic flux. As a result, we can do mechanical work with this flux.

This discovery was electromagnetic induction, and it was shown that electric fields and magnetic fields acted in the same way (the electromagnetic force). A few decades later, James Clerk Maxwell expressed this discovery with fundamental equations.

Who Devised the Current Alternating Current Distribution System?

Nikola Tesla was the first person who proposed to carry out electricity distribution with the alternating current. At that moment, he was working for Thomas Alva Edison's company.

In 1887, Nikola Tesla managed to build the first prototype of an induction motor. It worked thanks to a particular type of electric current, in which the electrons change their direction according to recurring alternations.

Tesla realized that AC generators emitted an electrical flux that changed polarity several times over a certain period.

 小结：二人都贡献巨大。法拉第发明的交流电还不能实用，特斯拉将交流电广泛实用于民生。
