AIRCRAFT ENGINES—ELEMENTS OF ELECTRICITY APPLIED TO IGNITION SYSTEMS

Produced by the US Army air forces. "Presents an over-view of the basic principles of electricity and then by animation, diagrams, and commentary explains their application to the ignition system of an aircraft engine." "The film opens with a simple explanation of electric current, voltage, polarity of magnets, and magnetic fields. There follows a detailed explanation of electro-magnetic induction, and the induction coil and then shows these principles as they are applied in generators." "The film closes with an explanation of the basic principles as applied to the whole ignition system and its various parts." Indiana. "Useful in any discussion of the principles of electricity and their practical applications, useful in general orientation in the mechanism of aircraft engines." Central Washington college of educ.
