Navy Electricity and Electronics Training Series

The Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical- and electronic-related Navy ratings. Written by, and with the advice , senior technicians in these ratings, this series provides beginners with fundamental electrical and electronic concepts through self-study. The presentation this series is not oriented to any specific rating structure, but is divided into modules containing related information organized into traditional paths instruction.

The series is designed to give small amounts information that can be easily digested before advancing further into the more complex material. For a student just becoming acquainted with electricity or electronics, it is highly recommended that the modules be studied in their suggested sequence. While there is a listing NEETS by module title, the following brief descriptions give a quick overview how the individual modules flow together.

Module 1, Introduction to Matter, Energy, and Direct Current, introduces The Course with a short history electricity and electronics and proceeds into the characteristics matter, energy, and direct current (dc). It also describes some the general safety precautions and first-aid procedures that should be common knowledge for a person working in the field electricity. Related safety hints are located throughout the rest the series, as well.
