| Physics for the Inquiring Mind (PHYS 105) Spring 2005 Exercises for Tuesday, February 8. [1] For the next four weeks, we'll be working with electric circuits. The circuits groups will be as follows: Cherry Garcia: Burke, Castellano, Gress, Laird, McClure Chubby Hubby: Cook, Hahnebach, Lilge, McArthur, Rutt Phish Food: Amerman, Cortese, Fricke, Kincaid, Myers Chunky Monkey: Arminio, Barnes, Barrish, Hoyt From Russia With Buzz: Berger, Lowery, Melrath, Stancick, Virus Karmel Sutra: Birth, Fretz, Merline, Miller, Wilson [2] Get into you new groups, and then send a group member up to get a kit. [3] Using your battery pack, bulb, wires, and a piece of aluminum, figure out whether electrical current passes through aluminum easily. If you wish to test the flow of electrical current through the aluminum, make sure that you design a circuit that forces the current to pass through the aluminum. If current passes easily through some substance, we call that substance a good conductor, or simply a conductor. [4] Determine whether wood is a good conductor. [5] Determine whether plastic is a good conductor. [6] Determine whether water is a good conductor. [7] Complete Experiment 1.11 on p. 386 of McDermott. [8] Read pp. 387-388 on Circuit Diagrams. [9] Complete Experiment 2.4 on p. 393. [10] If time permits, complete Experiment 2.6 on p. 395. [11] As Homework for Friday, February 11, do Exercise 1.12 (p. 388) and Exercise 2.2 (p. 391) in McDermott. |
