Question

What are the substances having high, low and moderate resistivity?​

Answer 1

Answer:

it depends on how many free electrons in it

Explanation:

if so much free electrons there will be less resistivity

Answer 2

A material with high resistivity means it has got high resistance and will resist the flow of electrons. A material with low resistivity means it has low resistance and thus the electrons flow smoothly through the material. For example, Copper and Aluminium have low resistivity. Good conductors have less resistivity.
