Graphs between electric current and pote...

Graphs between electric current and potential difference across two conductors `A and B` are as shown in (Fig. 3.49). Which of the two conductors has more resistance ?
.

Text Solution

Verified by Experts

As is clear from the graphs `A and B`, for a given pd, the current through the conductor `A` is less than the current through `B`, i.e., `I_A lt I_B` Since `R = V//I, R prop 1//I` for a pd, `R_A gt R_B`.
