N identical calls are cannected to from a battery. When the terminals of the battery are joined directly. When the terminals of the battery are joined directly (short - ciruited), current I flows in the circuit. To obtain the maximum value of I,A. all the cells should be joined in seriesB. all the cells should be joined in parallelC. two rows fo N //2 cells each should be joined in parallelD. `sqrtN` rows of `sqrtN` cells each should be joined in parlallel, given that `sqrtN` is an interger

Answer» Correct Answer - B
For series connection , `I_(min) = (N epsilon)/(Nr) = (epsilon)/(r )`
For parallel connection, `i_(max) = (epsilon)/(r//N)= (N epsilon)/(r )`
