1. Mount a conducting paper with two electrodes drawn on it on a board with contacts. Make sure that good contact is established between the contact points on the board with the two electrodes. Connect a battery between the two contact points. NOTE: Your setup may look slightly different than in the picture. Galvanometer Wires Battery Parallel Plates Sheet Voltage Probes Platform Connect a galvanometer or voltmeter between the two probe contacts. 2. With one of the probe contacts at a fixed position on the conducting paper, move the other probe around on the conducting paper until null reading is obtained in the galvanometer. Note the coordinates of the points which are at the same potential. Continue mapping all points which are at the same potential (null galvanometer reading) (at least 7 points). Replicate the electrodes on a graph sheet, draw the points of the probe contacts with the same potential and join them by a smooth line. This line represents one of the equipotential lines with a given constant potential. (tables and graph paper are attached) 3. Move the fixed probe to another position, repeat item 3, and obtain the equipotential line corresponding to the new potential of the fixed probe.. 4. Repeat 4 for several (total 7) fixed probe positions, thus mapping out several equipotential lines on the graph. 5. Change the conducting paper with a new design for the electrodes. Mount it and repeat 1 through 5 to obtain a map of equipotential lines for the new electrode configuration. 8251

Name. Date 6. From the graph of equipotential lines for the second electrode configuration, draw some electric field lines to represent the electric field in the region between the electrodes. (you can use a different color pencil or dotted lines to represent the field. What did you notice about the Electric Field lines and the Electric Potential lines? Summary. What did you learn from these measurements in 3-5 sentences?
