Course Description: This course is a study of three-phase alternating current circuits and single- and three-phase transformers and machines. The theory and operation of three-phase wye and delta circuits and the relationship of voltage, current and power in these circuits. The use of phasor algebra in the solution of alternating current problems is stressed as are the characteristics and use of electrical instruments such as voltmeters, ammeters, ohmmeters, and wattmeters. Students learn the theory and operation of transformers with single- and three- phase connections and are introduced to alternating current machines. Prerequisite: Elec 102

The graduate and the contractor can depend on the graduate having abilities and first-hand knowledge of the many facets of the electrical trade (e.g., commercial, residential and industrial electrical capabilities and knowledge, blueprint reading skills, estimating, job invoicing, codes and protocol, proper use and types of tools and equipment, ethics, etc.)
Course Objectives: Upon completion of this course, the student will: understand elemental electrical properties, electrical safety, ethics, electrical math principles, numbering systems and codes, basic quantities, meter usage and reading, taking standard measurements, electrical abbreviations, acronyms, symbols, and jargon, circuit conductors, connections, and protection, Ohm’s law and power formula, series/parallel circuit analysis and calculations, introduction to magnetism, solenoids, transformers, electric motors, resistance, inductance, and capacitance, circuit interfaces, residential circuits, commercial circuits, industrial circuits, fluid power circuits, audio systems, electronic control devices, and digital electronics circuits. The student will have demonstrated the ability to: • Define electricity and the basic electrical values o Voltage o Current o Resistance o Power • Calculate the electrical values and interpret the results of Ohm’s law • Calculate the electrical power of a DC circuit and components • Utilize basic electrical test equipment to measure voltage, current, and resistance using o Volt-Ohm meter (VOM) o Voltage indicator o Digital Multi-meter o Oscilloscope • Make basic electrical circuits and connections. • Read and interpret schematic symbols used in DC circuits
Course Policies: Course Organization: This course meets for four hours each week; two hours of lecture and two hours of lecture/lab. Lectures will consist primarily of instructor presentation using the white-board, projector, computer, & other aids, small-group activities, & lab application activities. There will be frequent opportunities for discussion & class participation. In-class activities & assignments will be extensions of topics introduced in lecture and/or reading assignments. There will be assignments that will be completed individually and/or in small-group format. Students are expected to bring their textbook, notes, calculator, and meter to all class sessions. Attendance & Participation: Attendance is required. Roll will be taken at each class meeting. Missing over three classes during the semester will probably reduce your course grade point unless there are extraneous circumstances that will have to be approved and make-up assignment and tests must be arranged with instructor approval. Students are responsible for all material presented in class. If a student must miss a class, it is that student’s responsibility to determine what information he/she missed. Prior arrangement for missed classes can be addressed to the instructor during office hours.
Late Work & Incompletes: Homework & lab assignments are accepted only on the scheduled due date. Unit tests are issued only on the scheduled test date. If the student misses a scheduled due assignment or test date, assignments will be accepted & make-up tests will be issued only if the student made prior arrangements with the instructor. Late work will be graded with a deduction of 5 points if turned in late on the due date, and 10 point deduction for each day following the due date if turned in late. Assignments will not be accepted after the end of the week. Make-up tests may not be the same test issued on the scheduled test date. They will be issued outside of class time and at the instructor’s convenience. It is the student’s responsibility to make arrangements for make-up work & tests. Exceptions to these guidelines are only rarely made on a case-by-case basis. Final Exams are issued only the scheduled exam date & can be made up only according to college policy. An incomplete (“I”) will be given only under extreme circumstances. To receive an “I”, (1) 80% of the coursework has to be completed, (2) all work has received an evaluation of a “C” or better, and (3) arrangements have been made prior to finals’ week. Safety & Health Issues: All students attending Montana State University - Northern are entitled to equal access to academic programs and services. By federal law, students with documented disabilities are entitled to reasonable accommodations in order to fully participate in the student experience. Students with disabilities are encouraged to advocate for themselves to the extent possible, and Disability Services provides support and assistance in determining what accommodations are best suited to each individual. It is recommended and encouraged that students contact their professor within the first two weeks of class. To be eligible for these special services students with disabilities must provide the required documentation. For more information and to register with Disability Services, please contact the Assistant Dean of Students in Cowan Hall 213. Academic Dishonesty: Refer to the student handbook for MSU-Northern’s official policy regarding academic dishonesty/plagiarism. When in doubt and concerned about academic dishonesty/plagiarism, (1) ask your instructor and/or (2) document the source. An act of plagiarism and/or dishonesty will lead to a failing grade on the assignment or in the course, as well as sanctions that will be imposed by the student judicial system. Academic dishonesty and plagiarism violate the Code of Student Conduct , are reprehensible and dishonorable, and are grounds for probation, suspension, and/or expulsion from MSU-Northern.

Category Descriptions: In-class Activities – directly related to the lecture &/or reading topic. These are given in class participation, a quiz, or small-group format & are completed in class. They are evaluated based on completion, participation, and content. Homework Assignments – extensions of concepts introduced in the lecture &/or reading topic. These are to be completed outside of class time & are due at the beginning of each unit. They are evaluated based on completion & content as well as having your name, class, date, etc. (If your name, etc. is not on the paper, you don’t get credit; just like if you don’t fill out your job-invoice, the boss doesn’t get paid for the time and materials and you don’t have a record of your work…so you don’t get paid). Lab Assignments – application of concepts introduced in lecture &/or reading topics. These are to be worked on during lab sessions & outside of class. They are evaluated based on the number of points correct divided by the number of points possible. Unit Tests – test understanding of unit objectives. These are issued periodically throughout the semester. They are evaluated based on a standard scale of number correct divided by number available.
Final Exam – tests understanding of course objectives. It will include items in typical test question form as well as application form. This is issued according to the college final exam schedule. It is evaluated based on a standard scale of number correct divided by number available.
