length l and resistance R is bent into a complete circle
A battery consists of a variable number ′n′ of identical cells (having internal resistance ′r′ each) which are connected in series. The terminals of the battery are short-circuited and the current I is measured. Which of the graphs shows the correct relationship between I and n?
