What is an insulator?

• A material or device that does not conduct electricity or heat

• A type of conductor

• Something that blocks sound waves

• ggjb

Give an example of a common insulator.

• Glass

• Rubber

• Metal

• Wood

Explain why insulators are important in the context of electricity.

• They prevent the flow of electric current

• They increase the flow of electric current

• They have no impact on the flow of electric current

• They are only used in specific situations

What are the characteristics of a good insulator?

• No resistance to the flow of electricity and heat, and high conductivity

• High resistance to the flow of electricity and heat, and low conductivity

• Medium resistance to the flow of electricity and heat, and medium conductivity

• Low resistance to the flow of electricity and heat, and high conductivity

How does the use of insulators contribute to safety in electrical systems?

• Insulators are only used for aesthetic purposes

• Insulators increase the flow of electricity to the ground

• Insulators prevent the flow of electricity to the ground

• Insulators have no impact on the safety of electrical systems
