Paper Description

Edit Paper Description Content

This paper covers the theory of electrical circuits and applications in signal processing, electrical machines and electrical power supplies.
The paper commences with a review of DC circuits, and quickly proceeds to AC circuit theory with complex impedance. Laplace theory is used to predict circuit performance. SPICE is used to simulate circuit operation and predict performance. The use of feedback to define amplifier performance is studied. In the second half of the paper circuit models are used to describe, control and manipulate power flow in three-phase power systems, electrical motors and transformers.

The learning outcomes for this paper are linked to Washington Accord graduate attributes WA1-WA11. Explanation of the graduate attributes can be found at: https://www.ieagreements.org/

Assessment

Edit Assessments Content

Laboratory notebooks may be taken into all assessments, exclusive of loose pages, foldouts, etc. All laboratory notebook pages must be bound and any attachments must be completely glued in place such that excisions and additions would be detectable.

Samples of your work may be required as part of the Engineering New Zealand accreditation process for BE(Hons) degrees. Any samples taken will have the student name and ID redacted. If you do not want samples of your work collected then please email the engineering administrator, Natalie Shaw (natalie.shaw@waikato.ac.nz), to opt out.

Workload

Edit Workload Content

The paper schedules a maximum of six contact hours per week for each student. Lectures (including tutorial) (3h) are scheduled every week and the labs (3h) are scheduled for ten weeks giving a total of 72 "contact" hours. A total of 36 hours is allowed for students to do back reading on topics covered in lectures and laboratory preparation. A period of 24 hours is allowed to complete the assignments. Two and a half day's study plus the 3h equivalent exam (the final test) gives a grand total of 155 hours.
