Franklin 1.8 is a Universal Macintosh application for plotting electric field lines and equipotential
surfaces around point charges. It is intended as freeware for
science education. It is not
however meant for commercial use or distribution without my permission.
The graphics seen at left were
created in an earlier Mac OS 9 version of Franklin, then exported through the clipboard to the
shareware program GraphicConverter where they were scaled to
a much smaller size.
