Module Description: An introduction to alternating current (AC) theory including impedance, reactance and resonance. The application of formulae and analysis techniques to AC circuits is explored.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Apply single phase AC theory to the solution of practical problems involving electrical AC quantities.
LO2 Describe electrical and magnetic terms and quantities. Perform fundamental calculations involving these quantities, and discuss practical applications.
LO3 Use simulation software and circuit analysis to calculate operating parameters of AC circuits including current, voltage, phase, root mean square (RMS) power and power factor and to confirm by experimentation and measurement.
LO4 Write a short laboratory report in accordance with accepted engineering professional standards
LO5 Conduct themselves in accordance with professional engineering standards while collecting and reporting on experimental data and in their dealings with others.
Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
