1. Electricity
Lights up your life!

2. What is Electricity?
It’s a form of energy produced when electrons flow from one place to another.

3. How does electricity work?
(flow of electrons creates a circuit from power source to device and back, as electrons flow through this circuit they generate heat, light or create movement through magnets)
(the circuit is a completed path of conductors that electricity can flow through)
Electrons flow through a circuit, or path, that generates heat, light or movement.

4. What is a conductor?
The musical director of a
symphony or orchestra?

5. What is a conductor?
Something that allows electrons to flow freely such as electrical wire or metal.
What are other conductors?

6. What is a resistor?
Something that slows the flow of electrons but does not stop it.

7. What is an insulator?
Material that does not carry electrons -- such as wood or plastic.

8. How do Conductors, Insulators and Resistors relate?
Boiling water on an electric stove top or hot plate.

9. Conductor, Insulator and Resistor
(A) Electrical coils are resistors (generate heat)
(B) Metal pot is a conductor (conducts the heat to the water)
(C) Pot handle is an insulator (protects your hand from burning)

10. What is an electric charge?
The charge obtained by an object when it gains or loses electrons.

11. What is an electric circuit?
The path along which electrons can flow.

12. What is an electric current?
The flow of electrons from negatively charged objects to positive.

13. What is an electric force?
The attraction or repulsion of objects due to their charges.

14. What is an electromagnet?
A temporary magnet created by the flow of electricity around an iron bar.
