| Module Description: |
In this module students will describe and define basic SI units and quantities. This module introduces basic resistive, capacitive and inductive circuits. The application of formulae and analysis techniques to these circuits is explored. |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
describe and define electrical, magnetic and physical terms and quantities and perform fundamental calculations involving these quantities. |
| LO2 |
apply DC theory to the solution of practical problems involving electrical quantities. |
| LO3 |
select appropriate electrical and electronic components based on their characteristics and construct basic circuits utilising these components. |
| LO4 |
build and construct basic series and parallel circuits in a electrically safe manner. |
| LO5 |
measure parameters within basic circuits to examine circuit/component behaviour |
| 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 CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s). |
| No recommendations listed |
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 |
