Description

This unit further develops the topics introduced in the preceding unit, ENS1162 Electrical Engineering 1A, and introduces some higher level concepts including impedance, first order system response, AC circuits, AC power, and semiconductor devices.

Prerequisite Rule

(Students must pass 1 units from ENS1162 AND For COURSE_CODE NOT IN K94, Y13, Y28, Y44, Y45, Y46, Y47, Y49, Y50, Y51, Y54, Y55, Y60, Y64, Y65, Y66, Y74, Y75 Do (Students must pass 1 units from MAT1137, MAT1236 OR Scaled Score in MAT3C/3D > 49.99) Otherwise true)

Equivalent Rule

Unit was previously coded ENS1252

Learning Outcomes

On completion of this unit students should be able to:

1. Analyse simple AC power systems.
2. Apply fundamental circuit analysis concepts to determine the operation and predict the performance of simple DC and AC linear circuits.
3. Conduct experiments on simple DC and AC electrical systems, and analyse and interpret the results of those experiments.
4. Undertake problem identification, formulation, solution and solution verification of small-scale DC and AC electrical circuits.

Unit Content

1. AC circuit analysis - phasor diagrams, resonances, instananeous and average power, maximum power transfer, AC superposition.
2. AC circuits - sinusoidal waveforms, sinusoids and phasors, sinusoidal steady-state circuit behaviour.
3. AC impedance - the impedance concept, impedance and admittance, resistance and reactance, impedance calculations, transfer functions and frequency response.
4. AC power systems - real and reactive power, power factor, three-phase systems, balanced and unbalanced loads, power measurement.
5. Capacitance and inductance - capacitors, inductors, DC steady-state behaviour, equivalent inductance and capacitance.
6. First order systems - RL and RC circuits, time constants, transient and steady state responses.
7. Transformer circuits - inductance and mutual inductance, ideal transformers, real transformers.
8. Transistors - structure and operation, large signal DC circuit models, universal curves, simple transistor circuits.
