ive electrode connected directly tothe earth at E^ and the positive electrode to a long con-ductor A L, which is also connected to the earth at E.The battery may be regarded as a machine which raises thepressure or potential of electricity from zero (or that of theearth) to a height equal to the… … Fig. 914. of potential between the conductor and the earth is thesame at all points along the conductor, and is representedby the distances between the line C D and the conductorA L. But when a current is allowed to flow along the conductor,the difference of potential between the conductor and…
