Basic Electrical Theory

These nine modules are presented in simple language and concentrate on presenting the concepts in ways that can be easily understood by people new to the industry.After completing these modules, a student should possess a working knowledge of basic electrical circuits as applied in air conditioning systems and have mastered basic electrical troubleshooting techniques. Each module is self-paced and contains a quiz and final exam for the section, each with reference to the appropriate section of the module, allowing students to evaluate their understanding of the concepts presented.

Introduction to Electricity


Module 1 introduces the student to electrical terminology and basicconcepts of electricity. This module is appropriate to students withlimited knowledge of electricity and covers Ohm's Law, power, series,and parallel circuits.

Electrical Components and Their Symbols


Module 2 introduces basic AC, magnetism, and common electricalcomponents. It begins the coverage of wiring diagrams and their symbolsby constructing a very basic circuit diagram.

Wiring Diagrams


Module 3 discusses safety practices and introduces additional electricalcomponents. A step-by-step construction of a simplified wiring diagram,covering power, control, and load circuits for a typical packaged airconditioner with electric heat, is developed.

Wiring Diagram Exercises


The fourth module covers step-by-step construction of a wiring diagramfor a heat pump to teach more advanced diagram-reading skills andcontrol circuit concepts.

Electric Meters and Their Uses


Module 5 discusses the construction of various types of meters andexplains their applications. Sample problems illustrate the use ofmeters in electrical troubleshooting and testing.

Alternating Current Fundamentals


The sixth module expands on basic AC concepts covered in Modules1 and 2 as the basis for understanding AC motors and AC power. Alsocovered are the basic concepts of motors and generators, capacitors,phase shift, and power distribution systems.

Motor Fundamentals and Motor Protection


Module 7 covers basic theory and operation of common single-phaseand three-phase AC induction motors, including motor starting circuits. The module also describes the various types of protective devices usedwith motors.

Electronic Devices and Circuits


Module 8 discusses basic concepts, packaging, and troubleshootingof electronic circuits used in comfort air conditioning. The modulecovers semiconductors, timing and sensing devices, and the use ofmicroprocessor controls in comfort applications.

Electrical Troubleshooting


Module 9 describes and illustrates techniques for troubleshootingelectrical and electronic circuits with a focus on control circuitsand motors.
