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.
Michael Faraday discovered benzene in the oily residue left behind from producing gas for lighting in London. 1831: Discovery of Electromagnetic Induction This was an enormously important discovery for the future of both science and technology. Faraday discovered that a varying magnetic field caused electricity to flow in an electric circuit. 1834: Faradayâs Laws of Electrolysis Faraday was one of the major players in the founding of the new science of electrochemistry. This is the science of understanding what happens at the interface of an electrode with an ionic substance.
