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) .

This unit covers following Essential Knowledge & Associated Skills elements:
