Three examples of non-conductors are rubber, glass, and wood. These materials do not allow electric current to pass through them easily due to their high resistance to the flow of electrons.

Electric conductors.
all metals are good conductors of heat and electric currents
Generally, non metals are non conductors (with exceptions such as graphite, fullerene etc)
Metals are good electric conductors.
Metals are generally good conductors of electricity, as they have free-moving electrons that can carry electric current. Nonmetals, on the other hand, are poor conductors of electricity, as they lack free-moving electrons to conduct electricity effectively.
In metal conductors, electric current is the flow of electrons.
metal
A loop of electrical conductors is called a circuit. It provides a path for electric current to flow.
All wires have a resistance, as does everything else in the universe. Conductors like metal and carbon generally have low resistances where as non conductors have a very high resistance. Think of it like friction, but electric.
Many - but not all - are poor conductors of electric current.
