Prediction 2-1: In the circuit in Figure 4-12, how do you expect the voltage across the<br />
battery to compare to the voltage across the bulb when the switch is open? Closed?<br />
Explain.<br />
7. Now test your <strong>pre</strong>diction by connecting the voltage sensors to measure the voltage<br />
across the battery <strong>and</strong> the voltage across the bulb simultaneously.<br />
8. Begin graphing, <strong>and</strong> close <strong>and</strong> open the switch several times. Print your graphs <strong>and</strong><br />
affix them over the axes above, or sketch them on the axes.<br />
Question 2-4: What do you conclude about the voltage across the battery <strong>and</strong> the voltage<br />
across the bulb when the switch is open <strong>and</strong> when it is closed? Are the graphs the same?<br />
Why or why not? What is going on as the switch is closed <strong>and</strong> opened?<br />
