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)

This course covers knowledge of the skill involved in operating a small business. It examines the necessary managerial and operational skills for proprietorship and the available resources for small business. Areas covered include self-assessment, planning, decision-making, legal forms of business, record-keeping, business insurance, taxes, financing, advertising, and promotion. A realistic business plan is developed.

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 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 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.

An introductory course investigating the construction, operation and control of electrical equipment installed and maintained by the various electrical trades. Topics pertain to direct current equipment and include shunt, series and compound motors and generators, manual and automatic D.C. controllers, stepping motors and D.C. meters. The paramount objective of the course is to acquaint the student with the practical aspects of related information such as magnetic flux, counter-electromotive force, armature and field currents, motor and generator loading conditions and the relationship of these electrical characteristics to specific types of mechanical, electrical and electronic controllers. Prerequisite: ET101 Technical Electricity 1 or permission of instructor. Corequisite: MA106 Technical Mathematics 2, or permission of instructor. (Spring semester only)
