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:
C
`I=(nE)/(n r)=(E )/(r )`
Current I is independent of number of cells .n.
