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
