Conductors and insulators

conductor is defined as

• materials that allow heat to flow through them easily.

• materials that allow electricity to flow through them easily.

• materials that allow electricity to flow through them hardly.

• materials that allow electricity to flow through them easily and hardly.

Insulator is defined as

• materials that allow heat to flow through them easily.

• that support the free flow of electrons from one particle of the element to another.

• that hinder and support the free flow of electrons from one particle of the element to another.

• that hinder the free flow of electrons from one particle of the element to another.

A few examples of an conductor are

• silver, aluminum, and iron.

• paper, wood, and copper.

• paper, wood, and rubber.

• silver, aluminum, and wood.

Conductors and Insulators  

• Electrons move freely within the Insulator.

• Electrons move freely within the conductor.

• Electrons move freely within the Insulator and conductor.

• protons move freely within the Insulator.

Conductors and Insulators  

• The electric field doesn’t exist (insulators).

• The electric field doesn’t exist (conductors).

• The electric field exists on the surface but remains zero on the  inside (Insulator)

• The electric field exists on the surface but remains zero on the  inside (Conductors and Insulator)

Conductors and Insulators  

• If a material permit heat to pass through it, then do not permit electricity to pass through it.

• If a material permit electricity and heat to pass through it, then do not permit energy to pass through it.

• If a material permit electricity to pass through it, then do not permit heat to pass through it.

• If a material permit electricity to pass through it, then it also permit heat to pass through it.

Which of the following materials are likely to exhibit more conductive properties than insulating properties?

• rubber

• silver

• Aluminum

• Wet skin

A conductor differs from an insulator in that a conductor 

• can become charged and an insulator cannot

• Electrons move easily through conductor material

• has an excess of electrons

• does not have any neutrons to get in the way of electron flow

One of these isolated charged spheres is copper and the other is rubber (Image).

• Sphere A is rubber

• Sphere A is copper

• Sphere A or B can be is rubber

• Nonsense!
