Describe the difference between insulator and conductor?
Insulators are materials that do not easily allow the flow of electricity, making them poor conductors. Conductors, on the other hand, are materials that allow the flow of electricity with little resistance. Insulators are used to prevent the flow of electricity, while conductors are used to facilitate the flow of electricity.
What are materials that don't allow electrons to flow freely called?
Materials that don't allow electrons to flow freely are called insulators. Examples include rubber, glass, and plastic. These materials have very high resistance to the flow of electrical current.
Materials that you can charge up by rubbing are they conductors or insulators?
Materials that can be charged up by rubbing (like wool or plastic) are typically insulators. Insulators do not allow electricity to flow easily, so when they build up a charge through static electricity, it stays localized on the object. Conductors, on the other hand, allow electricity to flow freely through them.
Is a sweater a good electrical conductor?
No, a sweater is not a good electrical conductor. Sweaters are typically made of insulating materials like wool or cotton, which do not allow electricity to pass through easily. Conductors allow electricity to flow freely, while insulators like sweaters block the flow of electricity.
What material will allow electricity to flow?
Electricity can flow through materials that conduct electricity, such as metals like copper, silver, and gold. These materials have free electrons that can carry electric current. Materials like rubber, plastic, and wood are insulators and do not allow electricity to flow easily.

Which type of material that allows electricity to flow but not as freely?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Good conductors are metals, such as copper or aluminum. Materials that allow the flow of electrons, but not as freely as good conductors are known as semiconductors. These are primarily silicon or germanium, that is "doped" with specific types of impurities to allow their current to be better controlled by the application of a voltage. Heat will also increase the flow of electrons in a semiconductor.
Materials that do not allow electric changes?
Materials that do not allow electric charges to flow freely are called insulators. Examples of insulating materials include rubber, glass, wood, and plastic. Insulators have high resistance to the flow of electricity, making them useful for protecting against electric shocks and preventing short circuits.
Is a conductor necessary for electricity to flow?
Yes, a conductor is necessary for electricity to flow. Conductors are materials that allow the flow of electric current, while insulators do not allow the flow of electric current.
What property of a material determines whether it will allow electricity to flow though it?
The electrical conductivity of a material determines whether it will allow electricity to flow through it. Materials with high electrical conductivity, such as metals, allow electricity to flow easily, while insulators, such as rubber or plastic, do not allow electricity to flow.
What will allow electricity to flow through it?
Materials that can conduct electricity, such as metals like copper and aluminum, have free-moving electrons that allow electricity to flow through them. These materials have low resistance to the flow of electric current, making them suitable for use in electrical circuits.
What kind of material does not let electric charges run through it?
Insulators are materials that do not allow electric charges to freely flow through them. Examples include rubber, plastic, and glass. These materials have high resistance to the flow of electricity due to their atomic structure.
What do we call materials that do not allow the flow of electricity?
Materials that do not allow the flow of electricity are called insulators. These materials have high resistance to the flow of electric current, preventing the movement of electrical charges through them. Examples of insulators include rubber, plastic, and glass.
