36 cells, each of internal resistance 
and emf of 1.5 V , are used to send maximum current through an external circuit of 
resistance. Find the best mode of grouping them and the maximum current through the external circuit.
Text Solution
Verified by ExpertsThe correct answer is:
D
Given, 
and 
Total number of cells, 
………. (i)
For maximum current in the mixed grouping,
………. (ii)
Multiplying Eqs. (i) and (ii), we get
and 
Thus, for maximum current there should be three rows in parallel, each containing 12 cells in series.
∴ Maximum current
