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.
Alfred P So â¦ uthwick, a member of the committee, developed the idea of putting electric current through a device such as a chair. The first electric chair was made by Harold P Brown and Arthur Kennelly. Both were employees of inventor Thomas Alva Edison and it operated on AC current.It was first used on August 6, 1890 for the execution of William Kemmler in New York's Auburn Prison.lfred P So â¦ uthwick, a member of the committee, developed the idea of putting electric current through a device such as a chair.
