Question

How does the resistance of an alloy vary with temperature?

Answer 1

Resistance in Alloys:

1. Alloys are metallic substances that are composed of two or more than two elements.
2. They can either be in the form of a compound or a solution.
3. Just like metals, alloys consist of free electrons as their charge carriers.
4. When the temperature increases, these free electrons start to move more randomly.
5. This causes more collisions within the alloy, resulting in less mobility and more resistivity.
6. But this additional disorder from the metals is very insignificant in an alloy.

Hence, the resistance of an alloy remains nearly unaffected by the change in temperature.
