I WONDER - What Is An Insulator?

The video explains the concept of insulators, which are materials that prevent the flow of electricity, contrasting them with conductors. It highlights the importance of insulators in ensuring safety from electrical currents and provides examples of insulating materials like rubber and glass. The video also discusses materials with poor insulation properties, such as water and damp wood, and emphasizes the critical role insulators play in preventing electrocution from electrical appliances.

What is the primary function of an insulator?

• To conduct electricity

• To generate heat

• To stop the flow of electricity

• To increase electrical current

Which of the following materials is a good insulator?

• Iron

• Water

• Rubber

• Copper

What role do insulators play in electrical safety?

• They increase the efficiency of electrical appliances

• They protect us from electrical currents

• They prevent electrical appliances from overheating

• They enhance electrical currents

Which material is NOT a good insulator?

• Glass

• Rubber

• Plastic

• Damp wood

Why are insulators important in everyday life?

• They help in conducting electricity efficiently

• They are used to store electrical energy

• They prevent us from being electrocuted

• They are used to generate electricity
