Question

I-V graph for parallel andseriescombination of two metallic resistors are shown in Fig. Which graph represents parallel combination? Justify.

Solution

When two resistors are connected in parallel, the equivalent resistance is smaller than each of the two resistances. Series connection the equivalent resistance to increase. Therefore, for the same p.d applied across combinations, greater current will flow parallel connection. Thus, BrepresentsI-V for parallel combination.
