This course introduces students to the fundamentals of electrical and electronic engineering. It provides the students with an understanding of basic electrical quantities, circuit elements and circuit analysis techniques. It also provides an understanding of the principles and operation of diodes (which are the basis of the ubiquitous DC power supply circuit) and operational amplifiers (which provide the easiest method to build an amplifier circuit). Specific topics include:

- Introduction to Electronics: Fundamental electrical quantities (charge, current, voltage) and circuit elements (resistor, capacitor, inductor, voltage and current sources).
- Circuit Analysis Techniques: Kirchhoff's voltage and current laws, Mesh current and Node voltage analysis, Thevenin and Norton Equivalent circuits, Superposition, Maximum power transfer, Wheatstone bridge.
- First-order RC and RL Circuits with DC inputs: Time constant, Transient and steady state responses.
- Diodes: Semiconductor materials, basic diode concepts and diode circuit modes, applications (rectifier and wave shaping circuits), Zener diodes, regulated DC power supply circuit.
- Introduction to Operational Amplifiers: Ideal op-amp, Basic Op-amp configurations, Summing point constraint. Basic amplifier circuits.

## Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

- Describe the basic circuit elements and calculate current, voltage and power for each element.
- Apply circuit analysis techniques (Kirchoff's laws, mesh current method, node voltage method, Thevenin and Norton equivalent circuits, maximum power transfer) to systematically solve electrical circuits.
- Analyse first-order switching circuits (RL and RC) and ideal op-amp amplifier circuits.
- Design a regulated DC power supply and construct it using prototyping boards.
- Explain in simple terms the electrical properties and circuit behaviour of resistor, capacitor, inductor, semiconductor devices (such as diode and zener diode) and ideal op-amp.
- Assemble circuits and take measurement of circuit variables using appropriate lab tools (such as oscilloscope, function generator, digital multi-meter, power supply and MOKUs). Simulate circuits using PSPICE. Calculate results using scientific calculator in a knowledgeable and confident manner.
- Collaborate for the purpose of taking measurements in a lab environment and lab report preparation.

## Other Information

- This course follows the textbook very closely and makes heavy use of the associated Mastering Engineering for Electric Circuits. While additional resources (including weekly problems, handouts and solved examples) will be provided during the semester to supplement the textbook, there is no substitute to reading the material from the textbook. Hence, all students must purchase the textbook (hardcopy or electronic) for their learning.
- To pass this course, students need to attend and complete at least 8 out of the 9 Labs, including HLab5.

## Indicative Assessment

- Mastering on-line assignments (8 assignments) (15) [LO 1,2,3,4,5]
- Laboratories (2 computer labs, 7 hardware labs) (25) [LO 1,2,3,4,5,6,7]
- Mid-sem Exam (20) [LO 1,2,5]
- Final Exam (40) [LO 2,3,4,5]

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.

## Workload

- A nominal workload of approximately 13 hours/week including the following: 2 x 2hr lectures/week, 10 x 10-20min online lectures, 9 x 3hr laboratories, 8 x online Mastering tutorials (2-6 hours each) and 11 weekly problems (1-3 hours each).
- Weekly average contact hours will be 7 hours (2 x 2 hour lectures and a 3 hour laboratory).
- Expected non-contact (self) study hours are 1-6 hours/week.
