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.

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 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 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.

This introductory course investigates 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 DC controllers, stepping motors, and DC meters. It emphasizes the practical aspects of 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. Corequisite: MA106 Technical Mathematics 2.

Ths course is designed to combine related information pertaining to AC machinery, electromechanical controllers, transducers, and electronic controls with the practical skills of equipment selection, installation, wiring, troubleshooting, and maintaining the machinery control systems currently used by industry. Topics include single and multiphase alternators, motors, transformers, and meters. Methods of machinery control include across-the-line starters, control relays, voltage and current transformers, limit switches, electronic switching, and speed or rotation sensors. Prerequisite: ET102 Technical Electricity 2, ET131 Electrical Machinery and Controls 1, MA106 Technical Mathematics 2.
