SECTION V: Procedure V-0: We will use the three patterns shown in Fig.0 and one of the patterns shown in Fig. 1 to study equipotential surfaces and electric field lines. The patterns are pre-drawn on separate sheets of graphite paper using a conductive nickel spray paint. Please try not to rub or excessively touch the paint, as this may reduce its conductivity. Graphite paper No.1 Graphite paper No.2 Graphite paper No.3 Fig.1 Fig.2 Graphite paper No.4 Graphite paper No.5 V-1: Use graphite sheet No. 1 shown in fig.1. Use the circuit shown in fig.3 to find a point at potential V = 2 Volts as follows: You scan the graphite paper with the probe tip A of voltmeter electrode until the voltmeter reads 2 Volts. You then insert the tip in the graphite paper 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. Using a pencil, label each group of points with the corresponding value of V. V
