Conductors & Insulators Sort

Front

What is a conductor?

Back

A conductor is a material that allows the flow of electric current or heat through it easily. 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 wood.

Front

Why are metals generally good conductors?

Back

Metals have free electrons that can move easily, allowing them to conduct electricity and heat effectively.

Front

What are some common examples of conductors?

Back

Common examples of conductors include copper wire, aluminum foil, and gold.

Front

What are some common examples of insulators?

Back

Common examples of insulators include rubber, plastic, glass, and wood.

Front

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 role do insulators play in electrical circuits?

Back

Insulators are used to prevent the unwanted flow of electricity, protecting users and ensuring that current flows only through intended paths.

Front

Can insulators become conductors under certain conditions?

Back

Yes, insulators can become conductors if subjected to high enough voltage or temperature, which can cause breakdown.

Front

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

Back

In conductors, electrons can move freely, while in insulators, electrons are tightly bound to their atoms and cannot move freely.

Front

What is the significance of using insulators in household appliances?

Back

Insulators are crucial in household appliances to prevent electric shocks and ensure safety by containing the flow of electricity.
