Use the model below to test your prediction about how wire length affects current.
When you were examining wire width, you compared data with other classmates to come up with a more accurate measurement representing current. Now you can use the modeling tool below to run multiple trials and aggregate your own data.
With your classmates, you found averages by conducting multiple trials and averaging the data collected across trials. Now, you'll be introduced to a tool that allows you to calculate a running average that will average all the measurements for current within one trial. To find that the average current within an individual trial, you can average all the individual current now measurements that you take.
In the workspace below is the model, now with an empty table and empty graph. As you run your model, the table will automatically update data from the model at each tick. Each time you press setup, you will begin a new “run” or trial of data collection. You can graph these data by pulling the variable headers from the table into an axis of the graph. You can also calculate specific information about the data by updating the table with formulas.
There are instructions on using the data table and graphing tools are embedded in the model's instruction window. You can move this window by dragging it's blue headers and also resize it by dragging any side of it. If you close the instructions, click the GUIDE button that looks like a book in the upper right-hand corner and select "Show Guide".
