                      Two students perform the experiments on series and parallel combinations of two given resistors and and the following V-I graphs. Which of the graph is/are correctly labelled in terms of the words series and parallel? Justify your answer .    

    Answer:

                      In the first graph, slope of I-V graph is resistance. Since in series combination, resistance is  more than the resistance in parallel combination, therefore, slope of I-V graph for series combination is more than the slope of I-V graph for parallel combination. Hence, graph is correctly labelled.               (1) In the second graph, slope of V-I graph is 1/resistance. Hence, second graph is also correctly labelled.                                             (1)
