Understanding Electricity: Conductors and Insulators

What role does electricity play in our daily lives?

• It is used only for cooking.

• It powers our homes and devices.

• It is used only for heating.

• It is used only for lighting.

What are materials called that allow electricity to flow easily?

• Insulators

• Capacitors

• Conductors

• Resistors

Why is copper commonly used in electrical wires?

• It is very cheap.

• It efficiently transfers electricity.

• It is very heavy.

• It is a good insulator.

Which of the following is NOT a good conductor of electricity?

What is the main characteristic of insulators?

• They allow electricity to flow easily.

• They have tightly bound electrons.

• They are made of metal.

• They are very heavy.

Which material is commonly used as an insulator in electric cords?

• To prevent electrical hazards.

• To make devices more colorful.

What can happen if you touch exposed wires that are not properly insulated?

• You will get a mild shock.

• The wires will become cooler.

• Nothing will happen.

• It can result in serious injuries.
