Cells and EMF Power is transmitted to the load if external resistance total internal resistance of all the cells R= nr / m
​
if n cells are in series and there are
′
m
′
rows of cells in parallel
(1) u rows each containing 6 cells is
required answer
​
because n=6 & m=4 R= 6 * 0.5 / 4 ​ =0.75 ohm perfect for the transmission at power to the load .750 ohm ​
