Part of the "A 3-D Demonstration" series. Explores basic electricity as it was perceived by Benjamin Franklin and other early theorists as well as the principles of positive and negative charge, conduction and induction, atoms and electrons, and elementary charge. Relates Coulomb's Law in detail, including the torsion balance experiment, that led to a breakthrough in scientific theory related to electricity. Accessibility options on the DVD are: (1) audio description, (2) expanded audio description, (3) English subtitles in a black box, (4) closed captions.
