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. -      ...
