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.
Tesla used this high frequency current to develop some of the first neon and fluorescent lights. 1881: The first public electricity supply. The first public electricity supply was generated in Godalming, Surrey using a waterwheel at a nearby mill.1883: Magnus Volks built the first electric railway. The first electric railway opened on Brighton seafront, built by electrical engineer Magnus Volks.881: The first public electricity supply.
