Table 2: Voltage Readings of Different AA Battery Combinations Battery Combination Voltage (V) 1.62 1 3.24 1 and 2 1, 2 and 3 4.87 1, 2, 3 and 4 6.49 Resistance (2) 967 Table 3: Resistor Data Slope (VIA) Current (A) 0.00166 0.00332 0.00498 0.00664 Percent Difference 1. Plot a scatterplot graph of Voltage vs Current from the Table 2 data and place this graph in the Graph section of your report (make sure Voltage is on the y-axis, and add a trendline). Construct your plot on a computer program such as Microsoft Excel. If you do not have a graphing program installed on your computer, you can access one on the internet via the NCES website or the Online Chart Tool. 2. What is the relationship between voltage and current? Use data from your graph to support your answer. 3. Determine the slope of the line and record it in Table 3. Click on a data point on the graph and Select Add Trendline under the Chart menu. Use the linear regression function and check the box to display the equation on the graph. 4. How does the value of the slope compare to the resistance you measured? Calculate the percent difference. 5. Use the results of your experiment to verify Ohm's Law. 6. How does adding more batteries affect the power dissipated through the resistor? Support your answer mathematically and record your answer in variable form.
