Question

a) The following table gives the value of electrical resistivity of some samples :
Sample
A
B
С C
Resistivity
1.6 x108
7.5 x 1017
44 x 10-6
Which one is the best conductor and insulator?​

Answer 1

Answer:

b is insulator and c is conductor

Explanation:

b is insulator because of high resistance of the material.

c is conductor because of low resistance of the material

as resistivity is directly proportional to the resistance of the material.
