| Module Description: |
An introduction to AC theory including Inductance, Capacitance. An examination of RMS Values. The application of basic formulae and analysis techniques to these circuits. |
| 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 and define electrical, magnetic and physical terms and quantities and perform fundamental calculations involving these quantities. |
| LO3 |
design circuits and examine component behaviour to determine parameters within circuits. |
| LO4 |
make meaningful measurements on electrical and interpret the information from these measurements to access the circuit and fault find |
| LO5 |
build and construct series and parallel circuits in a electrically safe manner. |
| 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 |
