…In 1834, he used a rotating mirror to measure the speed of electricity in a wire with three discharge gaps, and this technique was later used to measure the speed of light. In his research on telegraphy, he invented the magnetic needle telegraph with William Fothegill Cooke (1806-79) and conducted an experiment on undersea telegraphy in 1844. In 1843, he invented the variable resistor to verify Ohm's law, and popularized the Wheatstone bridge invented by Samuel Hunter Christie (1784-1865). … *Some of the terminology that mentions "Cooke, WF" is listed below.
