Conductors are
materials that permit electrons to flow freely
from particle to particle. … Conductors allow for charge transfer through the free movement of electrons. In contrast to conductors, insulators are materials that impede the free flow of electrons from atom to atom and molecule to molecule.
What are 2 conductors and insulators?
Conductors conduct electrical current very easily because of their free electrons. Insulators oppose electrical current and make poor conductors. Some common conductors are
copper, aluminum, gold, and silver
. Some common insulators are glass, air, plastic, rubber, and wood.
What is insulator with example?
The definition of an insulator is something that is used to keep heat or sound contained, or something that does not conduct electricity. Soundproofing material is an example of an insulator. …
Air, cloth and rubber
are good electrical insulators; feathers and wool make good thermal insulators.
What is conductor and insulator with example for kids?
Conductors are substances that an electric charge can pass through without difficulty. An electric charge cannot pass through an insulator easily. … Insulating materials, like
plastic
, are poor electrical conductors. They are used to prevent electricity from flowing to places where it is not needed.
What is an insulator in physics?
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.
What are 4 examples of insulators?

What is the best insulator for kids?
Wool, dry air, plastics, and polystyrene foam
are all examples of good insulators. Materials that do not insulate well are called conductors. Conductors have loose bonds that allow particles to move easily and transfer energy from one particle to the next. Metals tend to be very good conductors.
What is insulator and its types?
An insulator is one kind of material where the internal electric charge of this does not run freely; insufficient electric current will run through it in the power of an electric field. 2). What are the types of insulators are used in overhead transmission lines? They are
pin, suspension, strain, shackle, and stay
.
Is water an insulator?
Well actually,
pure water is an excellent insulator
and does not conduct electricity. The thing is, you won’t find any pure water in nature, so don’t mix electricity and water.
Is a good insulator?
A material that does not let heat and electricity travel through it easily is known as an insulator. …
Plastic, rubber, wood, and ceramics
are good insulators.
