Question

alloys are used as resistant materials instead of metals give reasons​

Answer 1

Alloys generally have higher resistance than the pure metals that they are made of, because the alloy disorder of the atoms causes additional electron scattering. Nichrome - which is an alloy of nickel and chromium, is usually a good choice.

Answer 2

Because alloys has both the mixture of metal and a non metal so it is used as a resistant and metals are good conductors of electricity.
