What are insulating materials?

• Insulating materials are substances that are highly flammable.

• Insulating materials are substances that are transparent to light.

• Insulating materials are substances that do not conduct electricity or heat easily.

• Insulating materials are substances that conduct electricity and heat easily.

What is an open circuit?

• A circuit that has a break or gap in the path of the current.

• A circuit that allows current to flow freely without any resistance.

• A circuit that is closed and allows current to flow continuously.

• A circuit that has a complete path for the current to flow through.

What is a closed circuit?

• A closed circuit is a circuit that only allows direct current to flow.

• A closed circuit is a circuit that does not allow any current to flow.

• A closed circuit is a path that is open and broken for an electric current to flow.

• A closed circuit is a complete and unbroken path for an electric current to flow.
