Ejs open Source Electric Field and Potential in a One-Dimensional of 2 Charged Particles Java Applet
In this simulation, you can investigate the electric field and the electric potential at various positions along a line, when there are either one or two charged particles on that line. In particular, you can explore the connection between the field and the potential.
The field and potential are represented in two ways. First, the table at the bottom shows the values of the electric field and electric potential at the position of the point charge. Values are given for the field and potential due to each charged particle individually, as well the net values.
The second way to represent the field and potential is graphically. You can look at both the graph of the electric field as a function of position, as well as the graph of the electric potential as a function of position. The graphs are probably most helpful in determining how field and potential are connected.
In addition, the arrows attached to the movable test charge show the field at the position of the test charge from the two charged particles.

Activities
This is challenging, but see if you can determine how field and potential are connected to one another. A good place to start is by turning on both of the charged particles, and giving them the same sign. This gives a place between the two particles where the net electric field is zero. At that same point, what is going on with the potential? Can you use that information to help you figure out how field and potential are related to one another?
