electric current

Question

A battery consists of variable number (n) of identical cells having internal resistance r each. They are connected in series. The terminals of battery are short-circuited and current is measured. Which of the graphs [Fig] gives correct relationship between i and n

Moderate

A
B
C
D

Solution

Here, $\frac{nE}{nr} = \frac{E}{r} = i = constant$
Thus the current is constant because it is independent of n. Hence the graph between n and i would be a straight line.
