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.
Nicolasâ¦ Joseph Cugnot of France built a steam  automobile in 1769.  Gustave Trouve of France designed and invented the first  electric car in 1881.  Karl Benz was the German mechanical engineer who  designed, patented and in 1885 built the world's first practical  automobile to be powered by a gasoline engine.
