Basic ac circuit theory.
AC power analysis.
Simple resonant and filter circuits.
Single-phase transformers.

LEARNING OUTCOMES
On successful completion the student should be able to:
1.
Apply AC circuit theory.
1.1 Simple AC series and parallel circuits are analysed using phasors and fundamental circuit
laws.
Range: Applications of Ohm’s law and Kirchhoff’s laws.
1.2 Simple AC circuits are Analyse using mesh and nodal analysis, and other circuit theorems.
Range: Multi-source circuits using current and voltage sources. The use of supermeshes and super-nodes. Thévenin’s theorem, Norton’s theorem, superposition, and
maximum power transfer.
2.
Perform calculations with power in AC circuits.
2.1 Power and power factor for simple AC circuits are calculated.
Range: Single-phase circuits.
3.
Analyse simple resonant and filter circuits.
3.1 Series and parallel resonant circuits are analysed.
Range: Simple RLC circuits.
3.2 The behaviour of simple filter circuits is analysed.
Range: Simple RC, RL, and RLC circuits.
3.3 The behaviour of simple filters using bode plots is described.
4.
Analyse single-phase transformers.
4.1 The operation of a transformer is described.
Range: Single-phase transformers.
4.2 Simple transformer characteristics are calculated.
Range: Single-phase transformers; ideal transformer equations.
5.
Describe the operation of motors.
5.1 The operation of a DC motor, single-phase AC motors, and stepper motors are described.

6.4
Demonstrate participation in activities that develop their personal generic capabilities.
Different forms of communication have been used.
A high standard of ethical behaviour was evident.
Interpersonal skills were practised.
Teamwork was evident through peer to peer interaction.
ASSESSMENT
Each Learning Outcome will be assessed by a combination of:
♦
performing circuit calculations,
♦
describing electrical and electronic systems, and
♦
performing laboratory exercises and interpreting the results.
The Generic capabilities are assessed formally through written work and formatively through class
activities. Students are expected to behave in a professional manner at all times, to be culturally
sensitive in their interactions with other people. All work submitted for marking that was performed
in an uncontrolled assessment environment is accompanied with a cover sheet declaring that this
is the students own work.
