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.
History of Alternating Current, Discovery and Distribution
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.
