Question

V-Igraph for two wires Aand B are shown in the figures . if both wires of same length and same thickness of thickness of which of the two is made of a material of high resistivity give justification for your answer ​

Answer 1

you have not attached the figure with the question.

but to identify the wire with higher resistant here is the clue :

the higher the slop of V-I graph the higher will be the resistivity
