A battery consists of a variable number ...

A battery consists of a variable number `n` of identical cells having internal resistance connected in series. The terminals of the battery are short circuited and the current `I` measured. Which one of the graph below shows the correct relationship between `I` and `n`?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
(d) If `n` batteries are in series than the circuit can be made
as`i=(nE)/(nr) implies (E)/(r )`
i.e., indpendent of `n`.
