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
