This course covers the four fundamental operations on integers, rational numbers, and real numbers. It includes the study of weights and measures, exponents and radicals, factoring, and linear equations, with an emphasis on technical applications.

This course is a continuation of MA105 Technical Mathematics 1, with further topics from algebra as well as from geometry and trigonometry, and an emphasis on technical applications. Prerequisite: MA105 Technical Mathematics 1.

An introductory course designed to provide the student with basic knowledge and skills necessary for personal growth in any electrical service technician program. The course includes an in-depth study of electron theory, Ohm's Law, series and parallel circuits, electrical energy and power relationships. Methods of generation of electromotive force, electromagnetism, motor principles and capacitance as these apply to D.C. circuits are included in the course. Uses, construction and calibration of voltmeters, ammeters and wattmeters are also investigated. Corequisite: MA105 Technical Mathematics 1, or permission of instructor. (Fall semester only)

A continuation of the introductory electrical course designed to reinforce and apply previously acquired information to alternating current (A.C.) circuits. This course investigates A.C. sine wave generation, mutual inductance, inductive and capacitive reactance, instantaneous values of voltage and current as well as real and apparent power. Uses, construction and calibration of A.C. metering equipment are an integral part of this course. Practical application of each topic in both introductory courses will be included in all laboratory experiments conducted by students. Prerequisite: ET101 Technical Electricity 1. Corequisite: MA106 Technical Mathematics 2, or permission of instructor. (Spring semester only)

This course covers the basic physics as applied to the refrigeration and air conditioning industry. Flaring and soldering techniques, compressor construction and domestic refrigeration, including characteristics of automatic controls as applied to domestic refrigeration. Prerequisites: MA105 Technical Mathematics 1 and ET101 Technical Electricity 1, or permission of instructor. (Spring semester only)

This course covers calculations of heat loss and gain, based on the residential and commercial level. Humidification, dehumidification, and air mixture problems are covered. Determination of U factors is taught to enhance the accuracy of overall calculations. Ventilation, exhaust loads, and standards are also taught. This course provides a working background in psychometrics. It begins with simple heat properties of air and works up to complex air mixture problems. Prerequisite: ET108 Refrigeration 1, (ET221 Heating & Air Conditioning may be taken concurrently.) or VT133 Refrigeration and Air Conditioning 1. (Fall semester only)

This course introduces combustion techniques in oil and gas furnaces. Cad cells, stack controls, oil primary controls and other safety devices are studied. Basic principles are applied to the solution of problems of heat transfer. Types of systems involving both residential and small commercial heating and air conditioning are covered. Split systems, hydronic systems, electric heat, heating and air conditioning controls, and package equipment are discussed. Heat pumps are emphasized. Prerequisite: ET108 Refrigeration 1. (ET220 Heating & Air Conditioning 1 may be taken concurrently.) or VT133 Refrigeration and Air Conditioning 1. (Spring semester only)

An introduction to the art of electrical wiring. Installation of electrical equipment provides the student with the opportunity to combine related information and manipulative skills with the practical aspects of wiring methods for complete electrical systems. All temporary laboratory controlled wiring is installed in compliance with the current National Electrical Code and provides experience in cable, conduit, surface raceway, service entrance, low-voltage control, annunciator and intrusion detection systems. Prerequisite: ET102 Technical Electricity 2, or permission of the instructor.
