QUESTION:-

100 cells each of Ent 5V and internal resistance 10 are to be arranged so as to produce maximum current in a 250 resistance. Each row contains equal number of cells. The number of rows should be​

ANSWER:-

Total no. of cells, = mn = 100

Current will be maximum when R = $nr/m; 25 = n x 1/m$

$n = 25 m$

From equation (i) and (ii)

n = 50 and m = 2
