tity of electricityseparated is proportional to the area. To make the electro-scope indication after separation as great as possible, it Wouldbe best to- grind together a zinc and copper plate as for thecondensing plates of an electroscope. If two such plates be sepa-rated by insulating handles,… … AB, acquires a higher potential than the other, BC. If nowwe could join A and C by a body which behaved only as a 122 THEORY OF THE VOLTAIC CELL. conductor, a flow of electricity would take place between Aand G tending to equalize their potentials; the contact at Bwould develope a fresh difference…
