An electric charge and field simulator allows viewers to place charges of selected signs and sizes on a map, and then to draw in electric field lines by clicking at various locations on the map. It is possible to create a plot of electric fields resulting from simple charge arrangements. We advise you read the brief explanation before using the applet.

A sophisticated shockwave tutorial describing how electrical depolarization and repolarization of heart tissue drives the heart and is recorded on a standard Electrocardiogram (ECG or EKG). Professor Sayegh, Physics Department, University of Michigan also has a site which explains some of the physics of an EKG.

The Hippocrates site contains other multimedia medical tutorials available to the public.
