Unformatted text preview: 1 ES4: PHY 152 Equipotential Surfaces and Electric Field Lines SECTION V: Procedure V-0: You have been provided with conductive paper upon which the three types of patterns shown in Fig.0 on three separate pieces of graphite paper using conducting silver paint. V-1: Use graphite sheet No. 1 shown in fig.0 with a white sheet of paper underneath. Use the circuit shown in fig.1 to find a point at potential V = 2 Volts as follows: You scan the graphite paper with the probe tip A of voltmeter electrode (by lightly dragging it across the surface) until the voltmeter reads 2 Volts. You then insert the tip in the graphite paper so as to make a small hole. Using the same method locate 10-12 points at V = 2 Volts. Repeat the process above for V = 4, 6, and 8 Volts. This will result in a series of holes in the white paper for each voltage. Label each group of points and your electrodes with the corresponding value of V on the white paper beneath the sheet with the painted on electrodes. Be sure to poke a few holes at the edge of each electrode so that you can tell where the electrodes are on the white piece of paper....
