1. CONSUMER ELECTRONICS Electric Fan

2. Morning Prayer (Our Father) Our Father, Who art in heaven Hallowed be Thy Name; Thy kingdom come, Thy will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our trespasses, as we forgive those who trespass against us; and lead us not into temptation, but deliver us from evil. Amen.

3. Yesterday………

4. External Parts

5. Fleming’s Left Hand Rule Force Current Magnetic Field Current

6. Objectives The students can identify the internal parts of an electric fan. The students can able to perform troubleshooting in the electric fan in setting the rotor’s speed.

7. Importance of electric fan Electric fan

8. Group Activity (Text Twist) E ach group will rearrange the letters to form a words that i will discuss for the topic of the day . ( 5 minutes ) After forming a words kindly paste those words in the illustration board.

9. What is Electric fan? It is a type of electronic appliances that is run by an electronic motor.

10. Purpose Of The Electric F an To convert electrical energy to mechanical energy. Electrical Energy Mechanical Energy

11. To make consumers feel comfortable during hot seasons or summer days.

12. Internal Parts Of The Electric F an

13. Selector Switch It is a part of electric fan that can intensify the produce air for the consumers. Rotary Switch Push Button Switch

14. Electric Motor It is the main part of the electric fan that produces mechanical energy to make the propeller rotate.

15. Rotor It is the movable part of the electrical motor that rotates

16. Stator It is a non movable part of the electric motor that provides electro magnetic energy to the rotor.

17. Copper Winding It is a set of copper wire that supplies electricity in the stator and rotor . Copper Winding in Rotor Copper Winding in Stator

18. Setting U p T he Speed O f The Electric Fan

19. Setting the speed of the electric fan requires : Electric Motor Selector Switch Handtools Terminal Block

20. Keep in mind that before doing this trouble shoot: Safety : Before working, the technician is need to focus to avoid accidents not just ourselves but also the safety of components.

21. Schematic : Read and understand first the schematic diagram. Preparation : Prepare the tools needed for the troubleshoot.

22. Let’s Start the Troubleshooting

23. Current and Resistance The Higher Resistance means a Low Current which will result slow rotation of the propeller.

24. The Lower Resistance means a Higher Current which will result in fast rotation of the propeller.

25. Fan Speed Control

26. Since that the no.1 in the selector switch has a slow rotation of rotor it means that the resistance needed is high.

27. No.2 in the selector switch will have a moderate resistance and the no.3 has a lowest resistance

32. After wiring…. With the use of tester, test the wiring if it has a right value of resistance. By connecting the test probes of tester in the line cord.

33. Let’s Have a Quiz

34. Rules No one is allowed to talk to their seatmates. Any form of cheating is not allowed during the quiz.

35. Do your best and Good luck
