Question

To get maximum current through a resistance of 2.5 Ω , one can use m rows of cells, each row having n cells. The internal resistance of each cell is 0.5 Ω . The values of n and m , if the total number of cells is 45 , are

TestHub · Accepted Answer

R = 2.5 Ω , r = 0.5 Ω no of rows = m , no of columns in each row = n i = n E R + n r / m total cells ⇒ m n = 45 for max. current; R = n r / m , m R = n r m = 3 , n = 15
