Unformatted text preview: The second piece of paper was similar, except it also had a large silver circle in between the two bars. This time, the entire grid’s voltage was measured including the points in the circle. This data was recorded in Excel, and two graphs created showing the voltage changes represented in both 2D and 3D. The one in 2D was drawn on, illustrating electric field lines, which lie perpendicular to the constant potential lines. The slope value for the first graph, along the center, is 0.4369, and the slope of the graph of the left ends was 0.3795. These values represent the magnitudes of the electric fields. There are a few sources of slight error. The inconsistency of the silver paint on the paper could contribute to slight variations. There were a few places where the silver paint had chipped off, forcing the reading to be moved slightly. Overall, the results seem pretty accurate....
