Conductors and Insulators

Front

What is the main difference between conductors and insulators?

Back

Conductors allow the flow of electricity, while insulators do not.

Answer explanation

The main difference between conductors and insulators is that conductors allow the flow of electricity, while insulators do not.

Front

Give an example of a good conductor of electricity.

Back

Copper

Answer explanation

Copper is a good conductor of electricity due to its high electrical conductivity, making it the correct choice.

Front

Explain why metals are good conductors of electricity.

Back

Metals have free electrons that can move easily through the material, allowing electricity to flow.

Answer explanation

Metals have free electrons that can move easily through the material, allowing electricity to flow.

Front

What is the role of electrons in conducting materials?

Back

They facilitate the flow of electric current.

Answer explanation

Electrons facilitate the flow of electric current by carrying the charge through the conducting material.

Front

Why do insulators not conduct electricity?

Back

Tightly bound electrons

Answer explanation

Insulators do not conduct electricity because their electrons are tightly bound, preventing the flow of electric current.

Front

How does the structure of conductors differ from insulators?

Back

Conductors have a structure that allows the flow of electrons.

Answer explanation

Conductors have a structure that allows the flow of electrons, which is why they conduct electricity.

Front

Common uses of conductors in everyday life?

Back

Electrical wiring, metal utensils, metal pipes

Answer explanation

Conductors such as electrical wiring, metal utensils, and metal pipes are commonly used in everyday life for various purposes.

Front

Explain the concept of resistance in conductors and insulators.

Back

Resistance is the measure of opposition to the flow of electric current in conductors and insulators.

Answer explanation

Resistance is the measure of opposition to the flow of electric current in conductors and insulators, making the second answer choice the correct one.

Front

Discuss the importance of understanding conductors and insulators in electrical safety.

Back

It helps in identifying materials that can conduct electricity and pose a risk of electric shock, as well as materials that can insulate and prevent electrical hazards.

Answer explanation

Understanding conductors and insulators helps in identifying materials that can conduct electricity and pose a risk of electric shock, as well as materials that can insulate and prevent electrical hazards.

Front

Material Two has very few electrons in its valence band. What is Material Two most likely?

Back

An insulator

Answer explanation

Material Two is most likely an insulator because it has very few electrons in its valence band, which makes it difficult for electricity to flow through.
