Current and Resistance 4/14/2014

We started with the electric potential fields analysis experiment.  In this lab, we took conductive paper that had a line and dot painted on it with metallic paint. A voltage supplier created electric potential difference between the line and dot via alligator clips. This voltage was measured as 15.02 V.  We then measured two points on the higher and lower voltage areas. The points measured on the higher voltage came out to be -0.62 V and the points on the lower voltage measured to be 1.37

We measure the electrical potential in various points in this in order to analyze a better understanding of the electrical potential difference and the relationship of the electrical field vs distance.

As the measuring distance increases, we plotted the measured values as follows:

Starting from the point, we measured the potential difference at 1 cm intervals going towards the line. We used excel to record the data and to create a  Potential vs Position graph as shown below.

The graph represents the the potential change with the distance from the power supply increasing. Looking at the data the positive charge goes from higher to lower potential.  Based on Eddie's epiphany, we conclude that the electrical potential goes up as the distance increases, therefore they have a direct proportional relationship.
