The V - I graphs for two resistors and their series combination are shown in Fig 5.23. Which one of these graphs represents the series combination of the two resistors? Given reason for your answer.
Text Solution
Verified by Experts
As slope of v-I graph `= V/I`= resistance R. From the given graphs, the slope of B is greater than that of A. So the resistance of B is greater than that of A. As resistance in series combination is more and in parallel combination is less, so B represents series combination and A represents parallel combination of resistors.
