Film: Elementary Electricity Film Title: Elementary Electricity. Level: Upper elementary-Adult. Length: 8 minutes. Black and white. Sound. This film is very simplistic,-perhaps too elementary for college students. It should be viewed before showing it to a class. It is a Navy film, (circa 1950?) Current (coulombs), resistance (ohms), voltage (volts) are all defined. Simple circuits, with batteries in series, resistors, ammeters, and voltmeters are hooked up. Ohm's Law is defined. That's about it.
