Who can tell me what the physicist Tesla is?

Physicist Tesla is a famous inventor.

Nikola Tesla (1856-1943) Tesla was an American inventor.

Tesla’s greatest contribution to science and technology was the creation of the alternating current system, which promoted the widespread application of alternating current.

Tesla’s research focused on solving the application of alternating current. At that time, driven by Edison, direct current was already in common use. But it has limitations. DC motors are expensive and cumbersome to use, requiring a separate generator for every square mile. In 1888, Tesla invented the AC polyphase power transmission system and received a patent for it.

In addition, Tesla also invented many other inventions, such as the amplifier in the telephone system. He proposed that the basic elements of radio communication are antennas, transmitting loops and receiving loops. He also invented high-speed radios for medical use. Frequency electrothermal therapy, manufacturing solitary light lamps, etc. *** Obtained 112 US patents.
