this is a legal remix version by lookang

changes made:

  1. added text array Q1, Q2, Q3 Q4 etc.
  2. added visualization colormode range from 0 to 9
  3. redesign the control panel to at the bottom
  4. table of the right
  5. made surface appear together with the charges for self manipulation to get 3D superposed view

Point Charge Electric Potential


The Point Charge Electric Potential model shows the electric potential produced by N point charges. Charges can be arranged in a ring, a line, or in parallel lines and the charge Q can alternate in sign. Custom configurations can be created by dragging particles or by entering xy and Q values into a data table. Blue (red) indicates a region of negative (positive) electric potential. The value of this potential V(x,y) is displayed in a text-box near the bottom of the view when the mouse is pressed.

Credits:

The Point Charge Electric Potential model was developed by Wolfgang Christian using the Easy Java Simulations (EJS) modeling tool version 4.3.4. You can examine and modify the model for this simulation if you have EJS installed by right-clicking within the program and selecting "Open Ejs Model" from the pop-up menu.

Information about EJS is available at: <http://www.um.es/fem/Ejs/> and in the OSP ComPADRE collection <http://www.compadre.org/OSP/>.
