The purpose of this index is to identify U.S. Navy and U.S. Air Force transparencies, films, and manuals which can be used by schools and colleges to teach basic electricity. Materials are classified according to 39 major categories including Electron Theory, Batteries and Battery Connections, D.C. Series Circuits, Network Theorems, Electromagnetism and Magnetic Circuits, Basic Electrical Indicating Instruments, Transformers, A.C. Motors, and Wiring Techniques. Some categories include films produced by other educational agencies or private firms. The six publications, three sources of transparencies, and 34 films classified in this index were selected by representatives of State Departments of Education in Washington, Idaho, Oregon, Colorado, and Utah. The sources have been assigned code numbers, and materials within code categories are listed by code number. (CH)
