Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

UEENEEE003B Solve problems in extra-low voltage single path circuits

Course Description

This unit covers determining correct operation of single source d.c. parallel and series-parallel circuits and providing solutions as they apply to various electrotechnology work functions. It encompasses working safely, problem solving procedures, including the use of voltage, current and resistance measuring devices, providing solutions derived from measurements and calculations to predictable problems in multiple path circuit.

Overview of Assessment

This is a progressive assessment, the students are required to undertake summative assessments as follows:
A. laboratory Journals.
B. Written Reports for one Assignment consists of parts A and B.
C. Closed Book Test and Closed Book Exam.


Assessment Tasks

1.  Laboratory exercises (15%)
Each student will complete five practical exercises designed to reinforce the theory topics taught during the semester.
Most practical exercises consist of two major parts:
Part A is a prior task includes only calculations (usually pre requisite for part B) and part B include measurements and graphs.
The results obtained in part B will be reviewed and compared with the calculations from section A.
These will be assessed progressively according to individual task criteria and each student is required to complete a short written report for each laboratory exercise.
All laboratory exercises must be undertaken according to safe working practice and performed according to specified laboratory standards and practice including calibration, measurement and accurate reading. This must include electrical measurement taken with safe working practice, meters properly calibrated, meter settings positioned for an accurate reading and accurate readings taken for all measurements.
2.  Project (10%)
A project has to be undertaken toward the end of the unit, in a controlled environment for the specified duration in order to perform tasks autonomously.
The project circuits can be constructed using either hard ware or MultiSim (design / test) simulation computer package. Each student will complete all parts of the project individually and will be asked by the supervisor to demonstrate that the circuit is functioning according to specifications. Each student is required to complete a written report includes three major parts: calculations, circuit diagrams / measurement and results / conclusion.
3  Written Test (25%)
Total = 50%
Possible total Mark = 50

Students must obtain at least 50% of the total mark for each assessment in order to pass the comptency successfuly.

This comptency is taught in conjunction with "UEENEEE003B" Solve problems in electrical circuits and with "UEENEEE001B" Apply OHS practices in the workplace therefore teaching schedual and assessments include three comptencies under the cluster title: Electrical Fundamentals & OHS.
