The vibrations of the voice converted into an electric current traveled from the transmitter to the receiver. The transcontinental telegraph finished in October 1861, was the line that served for immediate communications in the United States because it connected the East part of the U.S, with the West in California. Both accomplishments greatly added business transactions and facilitated the transmission of information throughout the country during those years.
