COURSE NAME:
Circuit Analysis I (3 Credits)
COURSE DESCRIPTION:
Topics under study in ELT 111 introduce students to theory and principles of circuit analysis such as series, parallel, and series/parallel dc circuits, as well as network theorems. Topics such as Ohm’s Law, Kirchhoff ‘s Current and Voltage Laws, and Current and Voltage dividers are covered in detail. To supplement the lectures and textbook problems, additional study materials, sample test, lecture notes, and other internet resources can be found at http://sst.nsu.edu/elt111.
METHOD OF INSTRUCTION:
Instructional methods to be employed in the course are lectures,
demonstrations, class discussions, group discussions, drills, and class work.
PRE/CO-REQUISITES:
MTH 151
COURSE RATIONALE:
ELT 111 is a required program core course which introduces direct current while applying the concepts learned in MTH 151. This course will act as a springboard for subsequent electronics courses such as ELT 212, 313, and 499. This course introduces the student to methods of circuit analysis used today, therefore an additional rationale for this course is the practical application that students will need when entering the technology workforce.
COURSE GOALS AND INTENDED OUTCOME:
By the end of the course, students will be able to:
Analyze an array of series, parallel, and series/parallel circuits.
Calculate circuits using various Network Theorems.
Interpret Network theorems and analyze them by applying them to the circuits.
Explain relationships between voltage , current and resistance in series, parallel, and series/parallel circuits.
Explain the application of Kirchhoff’s Laws and their place in electronics circuits.

GRADING STANDARDS:
Measurement of student comprehension and effectiveness of instruction, homework, quizzes, test and exams will be graded. Student participation in daily class discussions will also be used as measurement tools.
| EVALUATION CRITERIA |
| Homework, class participation | 15% |
| Quizzes | 10% |
| Tests | 30% |
| Midterm Exam | 20% |
| Final Exam | 25% |
Students must complete the course with an average of “C” or better to successfully pass this course. “C-“ constitutes a failing grade. Using the students’ cumulative average of these components, grades will be assigned using the following grading scale.
| GRADING SCALE |
| A: | 90 and above |
| B: | 80 – 89 |
| C: | 70 – 79 |
| D: | 50 – 69 |
| F: | 59 and below (including students who stop coming to class without officially
withdrawing from the university) |
| W: | Students must withdraw according to the procedures outlined in the current
course catalog or student handbook to receive a “W” grade. |
| The instructor reserves the right to revise the grading criteria as appropriate and will make reasonable attempts to notify students. |
Note:
Extra credit will be available at the sole discretion of the instructor.
Student absent for more than 20% of class meetings will not receive a passing grade in this course.
Continuous tardiness will not be tolerated and can affect grades negatively.
Late assignments will not be accepted except for excused absences.
Make-up examinations will only be permitted for excused absences, and must be completed on the first day the student returns to class.
An incomplete grade will only be permitted under extreme extenuating circumstances at the discretion of the instructor.
SUCCESS TIPS
In addition to good attendance and completion of all assignments, planning and self-management skills, good study habits, good time management and a good attitude will greatly increase the likelihood of success in this course. Students needing assistance with any of these success tips need only ask. Norfolk State University, along with your instructor, is committed to doing whatever is necessary to help you achieve your academic, and ultimately your career goals.
