Learning Outcomes

  • At the conclusion of this course you should be able to:

  • LO1: Apply circuit analysis methods to determine current flows, voltage distributions, and power absorption for direct-current (DC) and alternating-current (AC) circuits (WA1)

  • LO2: Model circuit components and sources using mathematical techniques and apply numerical simulations using modern circuit simulation packages to solve these models (WA1, WA5)

  • LO3: Use different methods, laws, rules and theorems to analyse, troubleshoot, simplify and design complex electrical circuits, accounting for transient, dynamic behaviour and the frequency response of these circuits (WA1, WA2, WA3, WA4)

  • LO4: Communicate circuit behaviour effectively to aid circuit and filter design using analytical and visual techniques (WA10)

  • LO5: Identify the applications and limitations of current and emerging components and analysis techniques in the design of electrical circuits (WA3, WA5, WA12)
    • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:

      Critically competent in a core academic discipline of their award

      Students know and can critically evaluate and, where applicable, apply this knowledge to topics/issues within their majoring subject.

      Employable, innovative and enterprising

      Students will develop key skills and attributes sought by employers that can be used in a range of applications.
