To get a maximum current in an external resistance of `8Omega` one can use m rows of n cells (connected in series), connected in parallel. If the total number of cells is 64 each having an e.m.f. of 2V and interanl resistance of `2Omega` , then calculate the number of cells in each row and number of rows.
