To get the maximum current from a parallel combination of

n

identical cells each of internal resistance

r

and external resistance

R

, when

View answer and explanation

Correct option: B

R\,\, \ll \,\,r

The correct answer is

R\,\, \ll \,\,r

because maximum current is achieved when the external resistance is much smaller than the equivalent internal resistance of the parallel combination of cells.
