I have always been interested in the history of direct current (DC) and alternating current (AC), so the subject itself is very attractive to me, but if you are not interested in this subject and just want to watch movies, the audience may find it rather boring. It's quite boring... DC vs AC popular science knowledge: Positive. Negative or +. - sign is DC, and its current only flows in one direction and flows out in the other direction. The one marked with L.N is alternating current. DC could not carry out long-distance transmission, the limit distance at that time was only 1 km, and its fatal weakness was that a power plant had to be built for every kilometer; while the positive and negative voltage of AC voltage would alternately alternate, just positive, and instantly changed A negative electrode, suitable for long-distance transmission. Therefore, alternating current can more effectively realize national power transmission, and is conducive to economic savings. Then, when it comes to money and fame, there will be struggles. So it can also be seen that the "Battle of Electricity" is not just a matter of who invented what first, Edison and Tesla (Tesla as a supporting role directly led to the downplay of the dispute with Edison. These two people are the real history The technical core battle of the DC vs AC battle). Because current is not just current, but also involves things such as light bulbs, generators, transformers, and more. How to use the characteristics of these things to sell your own current is not only science, but also marketing, contacts, funds, skills, etc. It is not as simple as "Edison invented power supply, everyone has electricity". Where there are people, there will be contradictions such as competition, interests, reputation, face, etc.

The Current War: Director's Cut quotes

  • [first lines]

    Thomas Edison: To all whom it may concern, be it known that I, Thomas Alva Edison, submits on this, the 27th day of January, 1880, the application of this abstract to the Patent Office of the United States of America. The unique design of my invention is that of a glass vacuum tube which houses inside a thin cotton thread filament, the two lower ends of which secure respective posts, forming an arch shape. Details and schematic drawings follow exhibiting all aspects of the invention. But its purpose is simple, to give light.

  • George Westinghouse: It seems to me that Mr. Edison puts his name on everything because he's terrified of being forgotten. But if you want to be remembered, it's simple. Shoot a president. But if you prefer to have what I call a legacy, you leave the world a better place than you found it.
