The resistivity of an alloy is higher than its constituent metals. Give reasons.

Open in App

Solution

Alloys have higher resistivity than their constituent metals because of the following reasons:
Alloys have high melting and boiling points.
Alloys do not get oxidized easily.
In alloys, higher resistivity is caused by the additional scattering of electrons known as alloy scattering.
In fact, alloys have better properties than their constituent metals.
