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.
