Item Picture
written by Paul Falstad
This java applet illustrates electrostatic fields and potentials and static current distributions in two dimensions.  It offers a broad range of interactive simulations, from simple single and double charges to highly complex dielectrics and currents.  The user can charges, conductors, and dielectrics to the simulation. Explanations provide help for running the simulation and something about the physics.

This is part of a large collection of applets covering topics in  waves, sound electricity and magnetism, and quantum mechanics.
