Module Description: This is an introductory module on electrical principles specifically designed for level 8 Mechanical & Biomedical engineering students. It addresses circuit concepts which are fundamental to an understanding of electrical system behaviour. The module encompasses the concepts of current, voltage and power measurement in resistive dc electrical circuits; ac circuit analysis with complex impedances; transformers and rectification.
 
Learning Outcomes
On successful completion of this module the learner will be able to:
# Learning Outcome Description
LO1 Describe DC resistive circuit behaviour using nodal and mesh analysis with application to RC circuits.
LO2 Explain the concepts of voltage drop, current flow and energy storage/dissipation through measurement in resistors, capacitors and inductors.
LO3 Explain the concept of electromagnetic induction and its application to inductances and transformer action.
LO4 Calculate the complex impedance and power factor of single phase RC and RL circuit configurations.
LO5 Apply a laboratory based computer aided learning system with software menu driven plug-in circuit board modules for experimental validation of fundamental electrical circuit concepts.

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).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
