Two students perform experiments on series and parallel combinations of two given resistors R1 and R2 and plot the following V-I graphs. Which of the graphs is (are) correctly labeled in terms of the words ‘Series and parallel’? justify your answer.
In case of series combination, the effective resistance = R1 + R2 is more, hence slope of V – I graph will be more. It is otherwise in case of I – V graph. So, series and parallel are correctly marked in graph (ii).
