Learning Outcomes

Details of Learning Activities

Classroom tutorial activities to consolidate the theory of concepts of AC circuit analysis. Tutorials will include calculations of voltages, currents and transients using circuit theorems. Follwing topics will be covered: Kirchof Laws , Superposition Theorem, Mesh Analysis , Thevenin’s Theorem, Norton Theorem, Maximum Power Transfer, Frequency Response, Complex Impedance, Transients.

Practical activities are designed to develop skill in construction of electrical circuits and measurement of electrical quantities: voltage, current, resistance, using analog and digital multimeters, oscilloscope and other currently available measuring instruments. Focus of practical exercises is on determining correct operation of complex series-parallel power circuits and providing solutions as they apply to electrical power engineering work functions

Circuit simulation softwares are also used to verify results of calculations obtained by using of linear circuit theorems to quantify voltage, current, and power in AC linear circuits. Recommended Softwares are PSPICE and Multisim ( Electronics Workbench) .

Overview of Assessment

This course will be assessed through a range of practical exercises, assignments and progressive tests.

Written Assessment 70%
Written assessment on principles of AC circuit analysis involving: Superposition Theorem, Kirchof Laws, Mesh Analysis , Thevenin’s Theorem, Norton Theorem, Maximum Power Transfer, frequency response, complex impedance and transients. Two progressive tests will be conducted on calculating voltages, currents and transient variables for complex AC circuits.

Practical Exercises 10%
Laboratory exercises involving the design and construction AC circuits, development of testing procedures to verify the performance specification, diagnosis of faults in the systems and completion of commissioning process.
Exercises are designed to determine correct operation of complex series-parallel power circuits and to provide solutions as they apply to electrical power engineering work functions.

Exercises will be assessed progressively according to individual task criteria. All practical exercises must be:
- Undertaken according to safe working practice as specified by the School.
- Perform according to specified laboratory standards and practice including calibration, measurement and accurate reading. This must includes electrical measurement taken with safe working practice, meters properly calibrated, meter settings positioned for an accurate reading and accurate readings taken for all measurements.
