Introduction to Electrical Fundamentals

Introduction

Welcome to the first course in Downtime Reduction Methodology, Downtime Reduction Academy is designed to prepare electricians and PLC technologies to implement our Methodology and become familiar with all electrical engineering disciplines. This course covers Electrical Fundamentals and basics of electricity. It is designed to prepare you for other Downtime Reduction courses products. Upon completion of Electrical Fundamentals you will be able to:

•  Explain the difference between conductors and insulators

•  Use Ohm’s law to calculate current, voltage, and resistance

•  Calculate equivalent resistance for series, parallel, or series-parallel circuits
•  Calculate voltage drop across a resistor
•  Calculate power given other basic values
•  Identify factors that determine the strength and polarity of a current-carrying coil’s magnetic field
•  Determine peak, instantaneous, and effective values of an AC sine wave
•  Identify factors that effect inductive reactance and capacitive reactance in an AC circuit
•  Calculate total impedance of an AC circuit
•  Explain the difference between real power and apparent power in an AC circuit
•  Calculate primary and secondary voltages of single-phase and three-phase transformers
•  Calculate the required apparent power for a transformer

This knowledge will help you better understand customer applications. In addition, you will be better able to describe products to customers and determine important differences between products.

After you have completed this course, if you wish to determine how well you have retained the information covered, you can complete a final exam online as described later in this course. If you pass the exam, you will be given the opportunity to print a certificate of completion from your computer.
