5: W 4/11, 7: W 4/11I won't be in class today - I'll be administering a physics contest in the library all afternoon. Today, start by finishing the lab we started last class. Discuss with your classmates the results of your lab, and ascertain the proportionality relationship between voltage, current, and resistance, which we call Ohm's Law. (You should be able to write down the relationship as a proportionality with all three variables.) Then do these Basic Ohm's Law and Power Problems which will be collected by the sub-study teacher. There is information in this packet about what you should have gained from the lab in addition to information about how to calculate the power output of a circuit element. Handouts: Basic Ohm's Law and Power ProblemsHomework: Write down any questions you have about the work you did in sub-study, and finish any problems from the last page you did not get to on a separate sheet of paper. If you still have not completed the lab graphs and analysis of the data for proportionality relationships between resistance, voltage and current, do so on the graph paper provided. This lab will be collected and graded next time. |
