Question

The resistivity of insulators is of the order of
(a) 10-8 Ω-m
(b) 101 Ω-m
(c) 10-6 Ω-m
(d) 106 Ω-m

Answer 1

Answer:

It must be D

Explanation:

Answer 2

Solution : The resistivity of insulators is of the order of $10^{6}$ ohm-m

• Insulator is a material whose internal electric charges do not flow freely.
• Atoms in insulator are tightly bound which cannot easily move

• It is very difficult to conduct electricity under the action of electric field.
• That's why the resistivity of insulator is very high.
