What are some conductors and some insulators?
Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.
What is the best conductor and insulator?
In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them.
Is Crayon a conductor or insulator?
| Object | Conductor or Insulator? (circle one) |
|---|---|
| crayon | conductor insulator |
| piece of metal | conductor insulator |

How many types of insulators are there?
The five types of insulators are: Suspension insulators. Pin insulators. Strain Insulators.
What is a insulator in science?
Insulator, any of various substances that block or retard the flow of electrical or thermal currents. Different insulating and conducting materials are compared with each other in this regard by means of a material constant known as resistivity.
Is pencil A conductor or insulator?
Elements that can conduct electric current are generally metals. However, the nonmetal carbon in the form of graphite is a good conductor of electricity.
Is coin a conductor or insulator?
Coin – The coin is an electrical conductor. Pencil – The pencil is an electrical conductor. Eraser – The eraser is an electrical insulator. Dollar bill – The dollar bin is an electrical insulator.
What are some examples of conductors and insulators?
Conductors conduct electrical current very easily because of their free electrons.
What are 10 examples of insulators?
Teflon
What are the most common insulators?
Of the various types of home insulation, batts and blankets is the most common type. Coupled with fiberglass, it is the most popular kind used in homes today. It can be found with aluminum or cardboard facing or without facing of any kind.
What materials are good insulators?
Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand.
