Question

The V-I Graph for a series combination and for a parallel combination of two resistance is shown in the figure. Which of the two, A or B, represents the parallel combination? Give a reason for your answer.

Answer 1

The slope of V-I graph gives the resistance. Since the straight line A is less steep, its resistance is less. We know that, in a parallel combination, the equivalent resistance is less than in series combination. So, A represents the parallel combination.
