2.Definition of Insulator: An insulator is a material that does not allow electric current to flow through it. Insulators have tightly bound electrons that do not move freely, preventing the flow of electric current. 3.Flow of Electric Current: In conductors, electric current can flow because ...
Solids which have conductivity inbetween those of conductors and insulator , i.e., ranging from 10^(-6) to 10^4 "ohm"^(-1) m^(-1) are called semiconductors. The two main types are n-type and p-type.
