To get the maximum current from a parallel combination of n identical cells each of internal resistance r in an external resistance R, when

A

B

C

R=rR = r

D

None of these

Answer

Explanation

Solution

Cells are joined in parallel when internal resistance is higher then a external resistance. (R <<r)

i=ER+rni = \frac { E } { R + \frac { r } { n } }
