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. Prerequisite: An appropriate placement test result or MA045 Basic Math Skills or MA050 Introductory Mathematics.
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.
This introductory course provides the basic knowledge and skills necessary within any electrical service technician program. It includes an in-depth study of electron theory, Ohm's Law, series and parallel circuits, as well as electrical energy and power relationships. Also included are methods of generation of electromotive force, electromagnetism, and motor principles and capacitance as these apply to DC circuits. Uses, construction, and calibration of voltmeters and ammeters are investigated. Corequisite: MA105 Technical Mathematics 1.
This course is a continuation of ET101 Technical Electricity 1. It reinforces previously acquired information and applies it to alternating current (AC) circuits. It investigates AC sine wave generation, mutual inductance inductive and capacitive reactance, and instantaneous values of voltage and current as well as real and apparent power. Uses, construction, and calibration of AC metering equipment are an integral part of this course. Practical application of each topic in both introductory courses are included in all laboratory experiments. Prerequisite: ET101 Technical Electricity 1. Corequisite: MA106 Technical Mathematics 2.
This course covers basic physics as applied to refrigeration and air conditioning. It includes flaring and soldering techniques, compressor construction, and domestic refrigeration, including characteristics of automatic controls. Prerequisites:MA105 Technical Mathematics 1 and ET101 Technical Electricity 1. (Spring Semester)
This course covers calculations of heat loss and gain, based on the residential and commercial level. It addresses humidification, dehumidification, and air mixture problems, along with the determination of U factors to enhance calculation accuracy. It includes ventilation, exhaust loads, and standards, along with a working background in psychometrics. It begins with simple heat properties of air and concludes with complex air mixture problems. Prerequisite: ET108 Refrigeration 1, orVT133 Refrigeration and Air Conditioning 1. (ET221 Heating and Air Conditioning 2 may be taken concurrently.) (Fall Semester)
This course introduces combustion techniques in oil and gas furnaces.It covers cad cells, stack controls, oil primary controls plus safety devices. Basic principles are applied to problem-solving in heat transfer. Types of systems involving 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, along with heat pumps. Prerequisite: ET108 Refrigeration 1 orVT133 Refrigeration and Air Conditioning 1. (ET220 Heating and Air Conditioning 1 may be taken concurrently.)VT133 Refrigeration and Air Conditioning 1. (Spring semester)
This course is an introduction to electrical residential wiring. It covers all of the essential elements regarding electrical installations in the home, including code making bodies, devices, boxes, conductors, outlets, light fixtures, ceiling fans and service entrances. All temporary laboratory wiring is installed in compliance with the current National electrical Code, providing experience in cable, conduit, surface raceway, service entrance, low-voltage control, annunciator, and intrusion detection systems. Corequisite: ET101 Technical Electricity 1.
