Classification of materials based upon resistance
Classification of materials based upon the resistance:- 1. Conductors: - Materials which offer least resistance to flow of electrons through them. - Example: Silver,Copper,Aluminium - Resistivity range: 10^(-8) to 10^(-3) - Applications: Cables core etc. - Note1: Resistance of a conductors increases with the increase in temperature. - Note2: Human body and earth acts as conductors. 2. Insulators: - Materials which offer very high resistance to flow of electrons through them. - ...
