Question
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 ?
Options
A.
B.
C.
D.
Solution
If n batteries are in series than the circuit can be made as
