### Notes pb lab 04 go with the flow

1. 1. Go With the Flow
2. 2. TSWBAT:Demonstrate anunderstanding of StaticElectricity, Current andCircuits
3. 3. Key Objectives:Key Objectives:Identify the two types ofelectrical circuits– Parallel– Series
4. 4. Key Objectives:Key Objectives:Recognize how resistanceeffects current in each type ofcircuit
5. 5. Key TermsKey TermsCurrentResistanceResistorSeries CircuitParallel CircuitAmperes
6. 6. CurrentCurrentThe rate of flow ofelectrons througha conductor.– Current ismeasured inAmperes
7. 7. ResistanceResistanceAnything that inhibits or slowsthe flow of electrons through aconductor.
8. 8. ResistorResistorA device thatinhibits or slowsthe flow ofelectrons throughit.
9. 9. Series CircuitSeries CircuitProvides onlyone path forelectrons toflow through aconductor.
10. 10. Series CircuitSeries CircuitA breakanywhere in aseries circuitwill end theflow ofelectrons or“Lights Out!”
11. 11. Parallel CircuitParallel CircuitProvides morethan onepathway forelectrons to flowin a circuit.
12. 12. Parallel CircuitParallel CircuitA break betweenresistors in thiscircuit will notend the flow ofelectrons.
13. 13. AmperesAmperesThe rate of flowof electronsmoving past agiven point persecond (A) orAMPs
14. 14. Essential LearningsEssential LearningsWhen voltage is increased(increase the number of drycells) in series and parallelcircuits, current increases.– This is called a DirectRelationship
15. 15. Essential LearningsEssential LearningsWhen resistance is added in aseries circuit, the current flow isreduced or decreases andcontinues to do so as you addresistance– This is called an Inverse/IndirectRelationship
16. 16. Essential LearningsIn this situation as lights areadded to the series, all thelights dim and subsequentlights may not light at all.
17. 17. Essential LearningsWhen resistance is added in aparallel circuit, the current flowincreases because there aremore pathways for the current toflow– This is called a Direct Relationship
18. 18. Essential LearningsEssential LearningsIn this situation, all of the lightsshould be equal in intensity
19. 19. Well done….– Get ready forlab!!!
21. 21. Essential LearningsThank youagain!!!
22. 22. Before you Begin:Which one?
23. 23. For the remainder of classIf possible pair up with a table-mate and open the HOLTtextbook to page 482Buddy-Read pages 482 - 497
24. 24. Is it this one??
25. 25. Or this one?
26. 26. Well……
27. 27. Its…..
28. 28. This one!
29. 29. Parallel Circuit Notice how the actualdrawing differs from thediagram. Notice the straight linesand right angles atintersections You will use the zig-zagsymbol for your diagramsand a broken line for eachswitch.
30. 30. Exit TicketCompare and contrast a parallelcircuit to a series circuit.
