Question

list different factors affecting resistivity of electrical materials

Answer 1

The resistivity of semiconductors and insulators decrease with increase in temperature. Means the semiconductors and insulators are having negative temperature coefficient of resistance. Alloying is a solid solution of two or more metals. Alloying of metals is used to achieve some mechanical and electrical properties.

Answer 2

The factors that affect resistivity of electrical materials are:-

• Length of the material
• Area of cross section of the material
• Nature of the material
• Temperature
