# Demonstration Electrostatics Models

Examples of simulations to illustrate electrostatic concepts. Navigate to the simulations by opening the folder and then double-clicking on the green triangle to launch.

#### Standard Examples:

- Charge Ring Trajectory (Electric Field and Coulomb's Law)
- Electric Multipole Field (Electric Field)
- Linear Charge Gauss Law (Gauss's Law)
- Spherical and Cylindrical Symmetry (Gauss's Law, Potential, Associated Laboratory)

If you have EJS installed, you can see and edit the models included. Information about EJS is available at: <http://www.um.es/fem/Ejs/> and in the OSP ComPADRE collection <http://www.compadre.org/OSP/>.
