Unformatted text preview: put ground (what value of potential does this then assign to the output ground?) GENERALIZED PROCEDURE For both of the landscapes, you will find several equipotential contours by searching for points in the landscape at the same potential using the voltage sensor. After recording these curves, you will draw several electric field lines, making use of the fact that they are everywhere perpendicular to equipotential contours. END OF PRE-LAB READING E01-3 IN-LAB ACTIVITIES EXPERIMENTAL SETUP 1. Run LoggerLauncher from your desktop and select 802_Exp_01_2010.cmbl. 2. Plug the Vernier Differential Voltage probe into channel 1 and the Vernier +/- 10V Voltage probe into channel 4. Navigate to the Experiment menu, select “Set Up Sensors,” and select “Show All Interfaces.” Click on the sensor icon in the CH 4 box and select “Analog Out.” Set the waveform to DC Output and the amplitude to 4V (the maximum allowed voltage). If you wish, zero the Differential Voltage probe by clicking “Zero” under the Experiment menu and selecting only this sensor (it is not necessary to zero the sensor as the purpose of this experiment is to obtain qualitative information about the equipotential lines, rather than exact data). One member of the group will hold these wires to the two conductors while another maps out the equipotentials. 3. Within the Experimental menu, select “Data Collection” and toggle “Continuous Data Collection.” 4. To ensure easy measurement, make sure your graph axes extend from 0-4V (set these parameters with “Graph Options” under the Options menu). MEASUREMENTS Part 1: “Standard” Configuration 1. Start with the dipole conducting paper landscape. 2. Use the voltage connectors to make contacts to the two conducting pads. The +/- 10V Voltage probe (CH 4) is the voltage source (since you set it to a DC Output of 4V), thus you should use the leads of this probe. 3. Connect the black lead of the other voltage probe (CH 1) to the black lead of the CH 4 probe. 4. Press the “Colle...
