Telegraph   Wheatstone-Cooke 1837
Telegraphic cable used for the connection between the train stations of Camden and Euston in London (1)

  

Notes: 1) This piece of telegraph cable was used in Cooke (1806-1879) and Wheatstone's (1802-1875) first experimental telegraph, which opened between Euston Square and Camden Town in London on 24 July 1837. The electrical current needed by the telegraph is carried by the 5 copper wires.

Once telegraphy had been invented, attention focused on finding the best technical solutions for transmitting signals over long distances.

Copper rapidly became the favorite conductor, because it has a low resistance and does not rust. Copper rapidly became the favorite conductor, because it has a low resistance and does not rust.
