1.	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.
Answer» Let for the given voltage V, the values of currents be `I_(1), I_(2)` and `I_(3)` for resistors 1,2,3 . `:. R_(1)= V/I_(1), R_(2) = V/I_(2) and R_(3) = V/I_(3)` From graph, we note that `I_(3) gt I_(2) gt I_(1)` `:. R_(3) lt R_(2) lt R_(1)` Hence graph 1 reprsents the series combination of other two resistnace.
