Over the last century or so, electricity has become an increasingly important and integral part of our daily lives. Knowledge of the fundamentals of electricity and application is increasingly necessary not only for those of us who work in the electric power industry, but also for the general public.

In this four-module program on electrical fundamentals, we introduce for study the general physics or basic natural laws that govern the use of electricity. This material will serve as a solid foundation on which to build the more advanced concepts dealt with in our many other training programs.

In presenting this material, we have tried to limit mathematics and complicated calculations, preferring instead to demonstrate concepts by the use of powerful animated graphics. However, we cannot dispense with calculations altogether, so please stick with us; this material does get more and more interesting as we proceed.

This part answers such questions as what a voltage source is and where it comes from as well as how voltage is created. It discusses methods for creating voltage, Ohm's Law, and the formula for calculating equivalent resistance, covering also magnetism, magnetic fields, and protective relaying.
