2. Activity-Based Questions In this section, you will start by working with the Logger Pro file that has the movie inserted in it. The electrometer shown in the background has numbers that are too small to read, but you can easily see the deflection of the needle. However, separate Logger Pro voltage probe readings were recorded as the movie was made. In the file the movie and the voltage readings have been synchronized. Although the capacitor plates look as if they are in contact at first, they are actually separated by 0.625 mm or a "half turn." After a few seconds the left capacitor plate is charged to about 13 volts relative to the right plate. Then the spacing between the two plates is increased a half turn at a time. You can see this process by opening the Logger Profile and clicking on the Start button in the Replay window. (a) Enter data into Logger Pro for voltage vs. plate spacing: In use the Examine tool to find a typical value for the voltage between the plates at each spacing. Enter the results in the Manual Entries table below. Also sketch the resulting graph of Vvs. d. Note: We've assumed for you that when the plates are in contact at d = 0 mm the charges neutralize, so V = 0.0 v. Table 1-Manual Entries 60 Rotations D V_ readings (# of turns) (mm) (volts) 0.0 40 0.5 V_readings (volts) 1.0 20 1.5 2.0 Capacitor Spacing Idl (mml (b) Is this an ideal capacitor? Close your original Logger Pro file and then open a second file entitled . Enter the data from Table 1 into the designated columns manually. A graph of V_readings vs. d will appear. Use the Curve Fit tool in the Logger Pro Analyze menu to determine whether the graph seems to show a proportional relationship between Vand d. Hint: Do not perform a linear fit. Instead select Curve Fit from the Analyze menu and select a Proportional Fit (denoted y = Ad). Does the capacitor act like an ideal capacitor? Explain
