Activity #1: Spreadsheet

Estimate of the Potential from a Charged Ring:

We separated the charges into 20 intervals and then added the potential of each in point P.

When point P is instead near the top of the circle, the distance between the point and the charge, r,  varies.

 Electric Potential Lab

For this experiment we required a cork board, alligator clips, semi-conductive paper, a voltmeter and a power supply. With these materials, we set out to find the potential difference between two points.

The graph of our data suggested that as the separation distance increases, the voltage also increases. This graph is parabolic.

As a takeaway, we learned that potential, being a scalar quantity can be added in kind.
