Conductors and Insulators

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily. Examples include metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to flow through it easily. Examples include rubber, glass, and plastic.

Front

Which material is a good conductor of electricity?

Back

Aluminum can is a good conductor of electricity.

Front

Which material is an insulator?

Back

Paper straw is an insulator.

Front

True or False: Water is an insulator.

Back

False. Water can conduct electricity, especially when it contains impurities.

Front

Name a common use of conductors.

Back

Conductors are commonly used in electrical wiring to transmit electricity.

Front

Name a common use of insulators.

Back

Insulators are used to coat electrical wires to prevent accidental shocks.

Front

What happens when a conductor is connected to a power source?

Back

Electricity flows through the conductor, allowing devices to operate.

Front

What happens when an insulator is connected to a power source?

Back

Electricity does not flow through the insulator, preventing devices from operating.

Front

Give an example of a poor conductor.

Back

Wood is an example of a poor conductor of electricity.
