Electrostatic Potential Applet

The electrostatic potential at some point due to a point charge is given by: E = kq/r. If more than one charge is present, the total electrostatic potential at a point may be found by measuring the strengths of the individual electrostatic potentials due to each of the individual charges and then summing them. In this applet you may create a group of point charges and then plot the resultant electrostatic potential.
