light change of potential in passing from copper tozinc, but this we shall neglect for simpUcity. The equipotential surfaces willprobably then be somewhat as sketched in Fig. 3 *, all the surfaces startingfrom where the acid comes in contact with the zinc, some of the highestpotential passing… … Pig. 3. If this be the actual arrangement, then it is seen that the current, whichtravels round the circuit from zinc through acid to copper, is in oppositionto the E.M.I, between the zinc and acid, while the M.i. is related to the currentin the ordinary way. The energy will therefore pass outwards…
