Circuits, Conductors, and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows thermal and electrical energy to pass through easily. Examples include metals like copper and silver.

Front

What is an insulator?

Back

An insulator is a material that does not allow thermal and electrical energy to pass through easily. Examples include rubber, glass, and plastic.

Front

Which material is considered a good conductor of electricity?

Back

Silver is considered one of the best conductors of electricity.

Front

What happens when you flip a light switch on and off?

Back

You are closing and opening a circuit, allowing or stopping the flow of electricity.

Front

Name a common use of conductors in everyday life.

Back

Conductors are commonly used in electrical wiring to transmit electricity.

Front

What is the role of insulators in electrical circuits?

Back

Insulators prevent the unwanted flow of electricity, protecting users from electric shock and ensuring that electricity flows along the intended path.

Front

Can you name a common insulator found in households?

Back

Rubber gloves are a common insulator found in households.

Front

What is the difference between conductors and insulators?

Back

Conductors allow electricity to flow easily, while insulators resist the flow of electricity.

Front

Why is copper often used in electrical wiring?

Back

Copper is used in electrical wiring because it is a good conductor of electricity and is relatively inexpensive.

Front

What is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat.
