The inventor of electricity was Faraday. In 1831, Faraday discovered electromagnetic induction, but also found a way to make alternating current, and soon after, Faraday invented the world's first electric motor that can continuously generate electric current. Later, scientists from various countries made other motors through Faraday's motor principle.

1. When did electricity first appear?

Although electricity was invented by Faraday, its earliest appearance was not in 1831, but around 600 BC. At that time, the ancient Greeks discovered that when the resin rubbed against the fur, there was an attraction, which was actually static electricity, although it was also called electricity at the time. Later, researchers found pots with copper sheets in ancient Roman ruins. Researchers generally believe that this may be the earliest battery. By the 17th century, electricity was even more common, with not only ways to distinguish between positive and negative currents, but also insulating materials. Later, several scientists mentioned electricity in the book, which made people have a strong interest in electricity, and began to find and invent electricity.

The type of electricity

Electricity is divided into two types: direct current and alternating current. Although they are collectively referred to as electricity, the two are not the same. Direct current is mainly used in industrial and medical applications, and the current of direct current does not change over time, that is, direct current energy maintains a current all the time. The current of alternating current will change with time, so alternating current will be safer and more suitable for use in the home.
