1876 W. H. Preece & J. Sivewright Telegraphy 298 A current of electricity will continue to flow so long as a difference of temperature is maintained between the junction and the extremities. This current is named a thermo-electric current, and the two metals form what is known as a thermo-electric pair; a combination of these pairs forms the thermo-electric pile or battery.
