Question

The type of materials whose resistivity is affected by adding the impurity is known as _______________

Answer 1

Resistivity - A material's resistivity is a fundamental property that determines how well it resists electric current.

Explanation:

1. There are three types of material on the basis of electric conductivity i.e., Conductor, Insulator, and Semiconductor.
2. A semiconductor is a substance that has both conductivity and insulator characteristics.
3. Semiconductors are made by doping impurities like pentavalent and trivalent atoms.
4. The conductivity of semiconductors depends upon temperature and the number of impurities.
5. Increasing the impurities increase the conductivity of semiconductors.
   Hence, The type of materials whose resistivity is affected by adding the impurity is known as Semiconductors
