Volta created the first battery. He made a voltaic pile constructed of alternating discs of zinc and copper. With pieces of cardboard soaked in brine between the metals. The voltaic pile produced electrical current. The metallic conducting arc was used to carry the electricity over a greater distance. This voltaic pile was the first battery. It produced a reliable, steady current of electricity.
The telegraph uses electromagnetic induction in order to send messages across wire with an electrical current. Claude Chappe invented the Telegraph in 1794.
The battery uses electromagnetic conduction by being a place to store electricity and later be used. This provides an easy source for electricity. Alessandro Volta created the battery in 1800.
