Electric potential

     The above picture shows the data collected and the graph constructed from that data for the experiment we performed on Monday. The setup of the experiment involved a DC power supply which was set to 15 volts, a multimeter, and a sheet of conductive paper pinned to a piece of particle board. The positive end of the power supply was connected to a silver painted line on the paper, and the negative end was connected to a circular painted point on the paper. We began testing the potential at the circular point and moved the positive lead of the multimeter away from the circular point in 1cm increments until we reached the silver painted line. We recorded the potential for each of these distances in excel and constructed a graph of Potential vs. Distance, which can be seen in the picture.
