Question

resistivity of metal is a constant quantity prove it

Answer 1

Answer:

Explanation:

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. Insulators have a high resistivity. The resistivity of semiconductors lies between conductors and insulators. Gold is a good conductor of electricity and so it has low resistivity.
