Conductors and insulators

Front

conductor is defined as

Back

materials that allow electricity to flow through them easily.

Front

Insulator

Back

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

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

Back

silver

Front

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

Back

Electrons move easily through conductor material
