V – I graph for two conducting wires A and B are as shown. If both wires are of the same length and same diameter, which of the two is made of a material of high resistivity ? Give reasons to justify your answer.
Solution
Wire B.
For the conductors of the same dimensions greater the resistance, greater is the resistivity.
