The battle between AC and DC

In 1831, Faraday discovered the law of electromagnetic induction. The next year, French scientist Pixie invented the world's first generator based on the law of electromagnetic induction. It was an alternator. After Ampere's suggestion to improve the device, it became The first DC generator was made. Since then, engineers from various European countries have improved the generator... Early generators were mainly used for lighting, so this episode also devotes a considerable proportion of its space to telling everyone about it. Here is the history of modern lighting methods. I hope everyone can capture innovative inspiration from this interesting history of science and technology!
