Subject Title

Subject Description
This course begins the network analysis stream in the Technology program. All of the basic concepts of D.C. electricity are introduced at a math level consistent with that being done in MTH 155. Thevenin and Norton Theorems are covered in the D.C. Networks area, since they prove useful in applications of Time Constants and associated calculations in Inductor and Capacitor Charging and Discharging circuits.

Credit Status
One subject credit in Computer Engineering Technology, Electronic Engineering Technology programs, and Electronic Engineering Technician programs. 

One credit towards the Faculty of Continuing Education and Training, Applied Electronic Troubleshooting Techniques certificate program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Explain the concepts of charge, current, voltage and resistance as they relate on schematic diagrams.

2. Apply the five main circuit laws (Ohm's Law, Kirchhoff's Law, and Divider rules) to the analysis of resistive series, parallel, and series-parallel circuits.

3. Construct series, parallel and series-parallel resistive circuits in the lab from schematic diagrams using a breadboard and/or a computer simulation program.

4. Demonstrate the safe setup, verification, troubleshooting, and operation of the lab equipment including: digital multimeters, DC power supplies, oscilloscopes, and function generators.

5. Use network theorems (including Superposition and Thévenin's Theorems) to calculate voltages and currents in electric circuits, and demonstrate the use of these theorems through measurements and simulations in the lab.

6. Explain with the help of diagrams, the characteristics of DC voltage and current sources, and convert between these two source types.

7. Calculate energy, power, and efficiency in resistive circuits.

8. Use the Maximum Power Transfer Theorem to calculate values of source and/or load resistance.

9. Explain the characteristics of a capacitor as a circuit element, and determine the transient response of an RC circuit using lab equipment.

10. Explain the characteristics of an inductor as a circuit element and analyze parameters of basic RL circuits.

Cheating and Plagiarism
Each student should be aware of the College's policy regarding Cheating and Plagiarism. Seneca's Academic Policy will be strictly enforced.

To support academic honesty at Seneca College, all work submitted by students may be reviewed for authenticity and originality, utilizing software tools and third party services. Please visit the Academic Honesty site on for further information regarding cheating and plagiarism policies and procedures.

All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated.

Modes of Evaluation

  • Assignments are due at the beginning of the class on which they are due.
  • A late penalty of 10% per day is assessed for late assignments, including those not handed in at the beginning of class when due.
  • Material will not be accepted after one week following the due date and/or when the marked material is returned to students, whichever comes first.
  • Assignments are to be prepared by computer.

Absenteeism and Exams
  • Students should be aware that absenteeism almost guarantees an inability to achieve satisfactory grades.
  • Students who are absent for an examination due to an emergency (e.g., motor vehicle accident, hospitalization or death in the family) may provide official documentation within five days of the missed exam and be provided a deferred exam at a later date.  Official documentation includes a death notice or an original doctor’s certificate identifying the date, length of time expected absence and the specific reason for the absence.  Examinations missed without official documentation and approval result in a grade of zero.
  • There are no deferred options for missed tests.  The value of missed tests, at the discretion of the Faculty, will be added to other evaluation components

English Proficiency
  • All written work should demonstrate the following characteristics for clarity and conciseness:
    • writing is consistent with the rules of English grammar
    • spelling and punctuation are correct
    • sentences are structured correctly
    • main ideas are supported with specific, relevant examples and reasons
    • work flows logically through supporting statements/paragraphs
    • work is arranged in correct format (e.g., as a report, essay)
    • up to 10% of the final grade may be deducted on all work if the above English competencies are not met.

Format for Assignments
  • Students must use the standard, APA style for quoting sources.   Help is available at:

Laboratory Attendance

The laboratory component is essential and therefore it is strongly recommended  that you attend all labs.  Any missed labs must be supported with a legal document with three days of the lab.  Any student who fails to attend 2 scheduled laboratory classes for a 7 week subject and more than 3 laboratory classes for a 14 week subject will not pass the subject.   

Laboratory Safety
Students are required to review and understand the safety procedures and guidelines outlined on the first class and sign the sheet to this effect before beginning work in the laboratory.  Students must also wear a lab coat and safety glasses when conducting experiments.
A student who arrives without the proper safety equipment will not be permitted to participant in the lab but will be asked to leave the class.  The student will receive no grade for the lab missed.

Term Tests, Assignments or Quizzes - 40%
Laboratory Work/Tests - 40%
Final Examination - 20%
Total:  100%

Students must pass the lab portion to pass the course.
