Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat. Common examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that resists the flow of electric current or heat. Examples include rubber, glass, and plastic.

Why is aluminum foil considered a good conductor?

Back

Aluminum foil is considered a good conductor because it is made of aluminum, a metal that has free electrons that can move easily, allowing electric current to flow.

What is the role of conductors in an electrical circuit?

Back

Conductors provide a path for electric current to flow, allowing the circuit to function properly.

Front

What is the role of insulators in an electrical circuit?

Back

Insulators prevent the unwanted flow of electric current, protecting users from electric shock and ensuring that current flows only through intended paths.

Front

Which material is NOT a good insulator?

Back

Iron is not a good insulator; it is a metal and therefore a good conductor.

How does temperature affect the conductivity of materials?

Back

Generally, as temperature increases, the conductivity of conductors increases, while the conductivity of insulators decreases.

Front

What is the difference between a conductor and an insulator in terms of electron movement?

Back

In conductors, electrons can move freely, allowing current to flow. In insulators, electrons are tightly bound to their atoms and cannot move freely.
