1. BRAIN TEASER

2. #1 Why is the letter F like death?

3. #2 During which month do people sleep the least?

4. #3 Which three letters can frighten a thief away?

5. #4 What letter comes next in the following sequence? D R M F S L T_

6. #5 What do an island and the letter “t” have in common?

7. CAPACITANCE Start Here

8. WHAT IS CAPACITATORS? An electric component that temporarily stored charges within a circuit.

9. What is Dielectric? A two conducting plates facing each other and separated by an insulator.

10. Capacitance the amount of charges stored in a capacitator per unit of electric potential  

11. Example: Compute the capacitance if the value of charge stored is 0.3x C and the voltage supplied is 1x V   A battery connected to the plates of a 3.00 µF capacitator stores a charge of 27.0 µC. How much voltage is provided by the battery?

12. VARIABLE EFFECT ON CAPACITANCE Area of the Conducting Plate Increase Increase Decrease Decrease Distance between the Conducting Plates Increase Increase Decrease Decrease Type of Dielectric More conducting Decrease Less conducting Increase

13. Shape of Capacitators

14. Parallel-plate Capacitators the capacitance of parallel-plate capacitator is directly proportional to the area of the plates as well as to the distance between the plates. The voltage is directly proportional to the distance between the plates.

15. Cylindrical Capacitators Inner and outer cylindrical structures correspond to the plates of the parallel-plate capacitator.

16. Spherical Capacitators An internal spherical structure is one of the charged bodies of the capacitator.

17. Capacitators in a Circuit Start Here

19. Example: Compute the individual values and the total values of the capacitance, charge and voltage of the circuit.

20. Parallel Connection = … = =  

21. Example: Compute the individual values and the total values of the capacitance, charge and the voltage of the circuit.
