What else can I help you with?
What happens when current reaches a insulator?
When current reaches an insulator, the electrons cannot flow through the material because insulators have high resistance to the flow of electricity. This can lead to a buildup of charge on the surface of the insulator.
Can electrons move freely in an insulator?
No, electrons cannot move freely in an insulator. Insulators have a full valence band and a large band gap that prevents the movement of electrons through the material. This lack of mobility is what distinguishes insulators from conductors.
Why is quartz an insulator?
Quartz is an insulator because its crystalline structure does not have any free moving electrons that can conduct electricity. This lack of free electrons prevents the flow of electric current through the material, making it an insulator.
A body that has relatively few free electrons and offers comparatively great resistance to the movement of free electrons is a an?
insulator. Examples include rubber, glass, and plastic.
Is wax an conductor or insulator?
Wax is an insulator, meaning it does not conduct electricity well due to its molecular structure that does not allow for easy movement of electrons.
What happens when current reaches a insulator?
When current reaches an insulator, the electrons cannot flow through the material because insulators have high resistance to the flow of electricity. This can lead to a buildup of charge on the surface of the insulator.
Is the plastic or rubber around copper an insulator because it allows the flow of electrons?
No, it is an insulator because it DOES NOT allow the flow of electrons.
Is glass insulator or conductor?
Glass is an insulator, as it DOES NOT conduct current. It is a material which has no free electrons available to flow as electrical current. Conductors, like copper or aluminum, have free electrons, or electrons in the outer shells of their atoms that are easily knocked loose. These electrons flow from negative to positive when an electrical potential (voltage) is applied across the material. We call the flow of electrons "current".
Is a glass tube a conductor or a insulator?
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.
Is a glass tube a insulator or conductor?
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.

No, electrons cannot move freely in an insulator. Insulators have a full valence band and a large band gap that prevents the movement of electrons through the material. This lack of mobility is what distinguishes insulators from conductors.
Is a rubber band insulator or conductor?
A rubber band is an insulator as it does not allow electrons to pss through it
Why is quartz an insulator?
Quartz is an insulator because its crystalline structure does not have any free moving electrons that can conduct electricity. This lack of free electrons prevents the flow of electric current through the material, making it an insulator.
A material through which electrons do NOT easily flow is a what?
An insulator or a dielectric.AnswerInsulators behave in the way they do because they contain insufficient numbers of charge carriers to support conduction. It has nothing to do with electrons being 'unable to flow easily'!
Is plastic or rubber around copper wires an insulator because it allows the flow of electron?
No, it is an insulator because it DOES NOT allow the flow of electrons.
How many valence electrons does insulator have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
Is cardboard a bad insulator?
Card board does not have free electrons electrons to transmit charge
