If athe graph V-I shows that resistance of A is greater than B but if both materials are of same length and same thickness ,which of the two is made of higher resistivity​

Dear Student

As resistance is directly proportional to the resistivity of metal.
R = ρ L/A

As length and thickness is same, So the material having higher resistance have higher resistivity.

In given case as A has higher resistance so A has higher resistivity.
