Honors Physics reviewed over the conceptual and quantitative aspects of series and parallel circuits and that will lead nicely into the lab on Monday that compares the behavior of these circuits. Students then were given time in class to work through problems with combined circuits – circuits where both series and parallel elements are present. The answers for these are below and in the solutions key on the course website. Make sure you can evaluate these types of circuits – if you can work these successfully, the other circuit types seem much easier in comparison.
20C
- 27.8 ohm
- 26.6 ohm
- 23.4 ohm
- 50.9 ohm
- 57.6 ohm
20D
- 0.5 A, 2.5 V
- 0.5 A, 3.5 V
- 1.5 A, 6.0 V
- 1.0 A, 4.0 V
- 1.0 A, 4.0 V
- 2.0 A, 4.0 V
Chapter Review # 26
- 1.7 A
- 3.4 V
- 5.1 V
- 0.42 A
Physical Science B continued on with their circuit building and, at this point, most groups have successfully constructed and investigated light-emitting diodes, polarity, motors, conductivity of materials, generator function and other cool stuff. We will continue on with this Monday and, likely, Tuesday. The research pieces for the projects will not be due with the completion of the hands-on part. Students will have extra time to pull that information together.
No one else met today, so not much to report. Have a nice semi-long weekend!
Homework
Honors Physics A: Read lab protocol sheet. Complete 20C, 20D and Chapter Review #26 for Tuesday
Physical Science B: None, although students may wish to begin working on their circuit research
