Insulators & Conductors

Insulators and Conductors share two main differences. An insulator does not let electrons flow through it freely. Whereas a conductor lets electrons flow freely through it. An example of a Insulator that I came across today was a pencil, the reason a pencil is an insulator is because it is made wood and all wood stops the flow of electrons. An example of a conductor I came across today was a soda can, the reason the soda can is a conductor is because it is made of aluminum which is a metal and all metals let electrons flow through them therefore they are conductors.
