Question

How does the resistivity of alloys compare with those of pure metal form which they may have formed?

Answer 1

The alloys have a high resistance because the alloys are the mixtures of different metals hence the resistivity of different metals are different therefore the alloys have more resistivity than the pure metals

Answer 2

Answer:

BELOW GIVEN IS YOUR ANSWER

Explanation:

A metal has large number of free electrons and due to this they conduct current and heat.The resistivity if a material or conductor is the hindrance or resistance offered by its structure to the free electrons to flow.Generally pure metals have low resistivity as they have large number of free electrons and low hindrance due simple atomic arrangement but when two or more metals are combined then the atomic arrangement changes and this changes the number of free electrons as well as increases the hindrance to their flow.Therefore, the resistivity of alloys is more than its constituent metals.
