Question

B) the resistivity of metals is a constant quantity prove it.

Answer 1

Answer:

A material with high resistivity means that it has high resistance and resists the flow of electrons.  Material with low resistivity means it has low resistance and the electrons flow smoothly through the material.

example, Copper has low resistivity.  Conductors have less resistivity.  Gold is a good conductor of electricity and so it has low resistivity.   Insulators have a high resistivity
