In this portion of the lab you are testing the potential difference between various points on a resistive sheet surrounding two point sources that have a voltage difference of 8V supplied to them.
First click the "ooo" at the end of each terminal shown near the top and bottom of the mid-line to see that the potential difference between the terminal that is supplied +8V and the ground terminal is in fact 8V and the potential difference between the ground terminal and itself is in fact 0V, both as expected.
Then, proceed to test all other "***" points across the surface. Your finger or mouse pointer acts as the positive lead and the negative lead remains connected to the ground terminal, so that the actual resulting potential difference is whatever number is displayed for each point you view.
Be sure to first download the Data Sheet in Canvas for the Two Point Sources before you begin as you will be using the results on this virtual lab demo to fill out the Data Sheet and answer the questions in your lab packet. The points in this virtual lab are intended to be equal distance from each other in both directions to match the 1cm point spacing in the Data Sheet.
