Afton McKinney Lab Assignment: Ohm’s Law Laboratory Introduction This lab will verify and demonstrate Ohm’s law. In this lab, you will study how current, voltage, and resistance are all related to each other and also determine the unknown resistance. First, design an experiment you could construct that might measure current and resistance. What materials would you use? What would you measure? What results would you expect? What if the results were different; what would that indicate? Write down your answers; this information will be part of your lab write-up that you submit to your teacher. Description Developing a Hypothesis: According to Ohm’s law, the current, resistance, and voltage are all related to each other in a circuit. In this experiment, you will find the various values of current for the corresponding values of potential differences. The values of potential differences can be altered or changed by connecting different numbers of cells in a series. Create hypotheses of what you think the results of this experiment will be.

How will changing the resistance change the current for the given value of potential difference? Defend your hypotheses with your knowledge of current and resistors. Your answers will be part of your lab write-up that you submit to your teacher. Objectives: 1. Verify Ohm’s law, 2. Determine the value of unknown resistance. To view the items that need to be included in your lab write-up along with a grading rubric, please refer to the Guidelines for the Laboratory section in the orientation. Procedure Read the entire lab procedure and plan the steps you will take. 1.You will find the virtual lab on the next page. It may be helpful to download the Ohms Law Lab Report (also found within the virtual lab) before starting the virtual lab simulation. 2.Prepare data tables. 1.Prepare a data table for experiment –I using your spreadsheet program.
