CONDUCTORS AND INSULATORS

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

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

Front

Why is copper commonly used in electrical wiring?

Back

Copper is a good conductor of electricity, meaning it allows electric current to flow easily, making it ideal for electrical wiring.

Front

What are some common examples of insulators?

Back

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

Front

What happens in a closed circuit?

Back

In a closed circuit, the electrical path is complete, allowing current to flow and devices (like lights) to operate.

Front

What is the role of a conductor in an electrical circuit?

Back

The role of a conductor in an electrical circuit is to provide a pathway for electric current to flow.

Front

What is the role of an insulator in an electrical circuit?

Back

The role of an insulator in an electrical circuit is to prevent the flow of electric current, protecting users and components.

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 is the difference between a conductor and an insulator?

Back

The main difference is that conductors allow electric current to flow easily, while insulators resist the flow of electric current.

Front

Can you name a material that is both a conductor and an insulator?

Back

Some materials can act as both conductors and insulators depending on conditions, such as semiconductors like silicon.
