Conductors,Semiconductors, and insulators
defintions
conductor : is an object or type of material that allows the flow of electrical current in one or more directions
Semiconductors : a solid substances that has an conductivity between that an insulators and that of most metals
Insulators : a thing or substance used for insulation, in particular
Compare and contrasting
Comparing : they all have to deal with electricity
Contrasting: there conductivity is different. for example, conductor is very high, and insulator is very low, and semiconductor is very moderate
