In the parallel or multiple method of grouping, the coppers are all joined to one terminal and the zincs to another. This gives the same result  as if all the plates were in one large cell. The E. M. F. is the same as it would be for a single cell, while the internal resistance is less. Ohm's Law will be:

in which P is the number of cells in parallel. 

EXAMPLE. - Suppose the same 4 cells …. to be grouped in parallel and to be coupled to the same resistance. What will be the current?
