the label states;

The film, Principles of Electricity (1945) breaks down structure of matter into atoms and, by use of conventional symbols, shows the action of electrons within an atom. The principles involved in the flow of current are explained and a volt, ampere and Ohm are defined. This is a great film. I've done some minor electronics work in my profession and have a basic understanding of electricity, but this film taught me something new.

I would love to have seen this film years ago in junior or senior high. Why aren't films like this used to teach the youth of today?
