Unit description Unit description
This unit develops the fundamentals in electric and electronic circuits and the laboratory investigation and reporting. The unit covers the key electric circuit elements and their models, and analysing circuits including these models. Topics include: linear electrical components; energy dissipation, energy storage and power transfer; Kirchhoff's laws; transient versus steady-state. Linear electrical components include voltage and current sources, resistors, capacitors, and inductors. Time domain vs frequency domain circuit analysis, and impedance concept is introduced, leading to ac circuit analysis and ac power concepts.

Important Academic Dates

Learning Outcomes

On successful completion of this unit, you will be able to:

  • ULO1: Calculate the response of circuits composed of linear circuit elements with a source of constant energy to determine all currents, voltages and power.
  • ULO2: Apply the method of time domain analysis of circuits composed of linear circuit elements with a source of constant energy to determine all currents, voltages and power when an abrupt change is applied to the circuit.
  • ULO3: Analyse circuits composed of linear circuit elements with a source of energy with a sinusoidal time dependence to determine the circuit’s response in terms of current, voltage and power.
  • ULO4: Apply the method of frequency domain analysis and the Laplace Transform to determine the circuit response for all applied frequencies.
  • ULO5: Physically construct and experimentally characterise circuits with one or more linear components
  • ULO6: Write concise reports summarising methodologies used and the results obtained.

General Assessment Information

Assignment Tasks

Assignment questions will be posted on iLearn at least two weeks before their submission date. Assignment solutions will be posted within one to three days after the submission date. Submissions will not be accepted after the due date. All assignments must be submitted electronically through iLearn (in pdf format). Submissions are expected to be neatly written (or typed) in a logical layout and sequence. Markers WILL NOT grade poorly organised or illegible scans or drafts. The expected workload includes preparation of final copies and clear diagrams. Re-submissions will be permitted up to the original due date. All assignments should be prepared individually by you. It is expected that students consult tutors, lecturers or other students while learning the concepts, but copying assignments from others is not accepted. Students are expected to have read and understood the academic honesty policy.

 

Late submissions

Online quizzes, in-class activities, or scheduled tests and exam must be undertaken at the time indicated in the unit guide. Should these activities be missed due to illness or misadventure, students may apply for Special Consideration.

Should these assessments be missed due to illness or misadventure, students should apply for Special Consideration.

Assessments not submitted by the due date will receive a mark of zero.

 

Grading

In order to pass this unit a student must obtain a mark of 50 or more overall or obtain a passing grade P / CR / D / HD.

 

Supplementary Exam

If you receive special consideration for the final exam, a supplementary exam will be scheduled. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
