Noble gases are frequently used in tubes for many purposes, from lighting to switching. Pure noble gases are employed in switching tubes. Noble-gas-filled thyratrons have better electrical parameters than mercury-based ones.
The first electric motor able to turn machinery was built by William Sturgeon in 1832. In 1821, Michael Faraday built a machine that made a piece of metal move due to the flow of electricity. Although the amount of motion was small, this was the first published design of an electric motor. All subsequent developments in the use of electricity to make motors work came out of this invention. The first electric motor able to turn machinery was built by William Sturgeon in 1832.
Still life of the first electric light bulb, invented by Thomas Alva Edison in 1879 and patented on January 27, 1880. How Edison Invented the Light Bulb â And Lots of Myths About Himself. The electric light wasnât Thomas Edisonâs first invention, nor was he the first to create an alternative to gaslight. Electric lights already existed on a streetlight scale when, on this day in 1879, Edison tested the one he's famous for.
