7103: Electrical Fundamentals, Power and Power Factor  

In this four lesson program on basic electrical fundamentals, we will be introducing and studying the general physics, that is the basic natural laws which govern the application in utilization of electricity.

This material will serve as the solid foundation on which to build the more advanced concepts that are dealt with in our many other training programs.


  • Learn how to calculate impedance 
  • Understand the vector diagrams and the power triangle 
  • Understand what a voltage drop is and how you determine a sources voltage requirements 
  • Learn about the principals of operation of transformers and about the idea transformer, the autotransformer and the instrument transformer
  • Review transformer regulation and voltage regulation techniques


  • Lesson 1: The Impedance Triangle 
  • Lesson 2: Voltage Drop 
  • Lesson 3: Introduction to Transformers 
  • Lesson 4: Transformer Impedance and Regulation
