Practical activities are used to prepare students to work safely ( with OHS awareness) on simple extra-low voltage single path electrical circuits with problem solving nature followed by related questions to these practical activities. Work completion (calculation/results/measurements) will be documented to develop skills in safe testing.
Participate in individual and team problem solving scenarios and participate in supervised workshop practice in simulated workplace environment dealing with a range of practical exercises related to:
• Preparing to connect DC series and parallel 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 Assignmet consists of parts A and B.
C. Clossed book Test and Closed book Exam.


Assessment Tasks

1.Laboratory journals (18%)
Each student will complete nine lab jurnals (practical exercises) designed to reinforce the theory topics taught during the semester.
Most lab jurnals 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, documented 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 all the parts/tasks for each laboratory jurnal.
All laboratory jurnals 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. Assignment  Part A (5%)  and Part B (7%)
An assignment (part A & B) has to be undertaken in a controlled environment for the specified duration in order to perform tasks autonomously.
The assignment circuits can be constructed using either hard ware or MultiSim (design / test) simulation computer package. Each student will complete all parts of the assignment individually and will be asked by the supervisor to demonstrate that the circuit is functioning according to specifications. Each student is required to submit a written report includes three major parts: calculations, circuit diagrams / measurement and results / conclusion.
3. Closed book Test (20%)
Theoretical concept covered in weeks 1 to 8 will be assessed by a written test in week 9.
4.Closed book Exam (50%) 
Theoretical concept covered in weeks 9 to 17 will be assessed by a written test in the examination week. 

This Competency is taught in conjunction with EEET6780C “UEENEEE004B Solve problems in multiple path d.c. circuits" and OHTH5464C “UEENEEE001B Apply OHS practices in the workplace".
