Two students perform the experiments on series and parallel combinations of two given resistors R₁ and R₂ and the following V-I graphs.(attached below)
Which of two diagrams correctly represent the labels 'series and parallel' on the plotted curves ? justify your answer. please explain in the simplest way

By ohm's law, V=IR
In first graph slope= V/I=R. so greater the resistance, greater the slope or inclination. We know R in series is greater than in parallel so its inclination will be greater and thus the first graph.
The second case is total opposite.

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