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

MEM12024A Perform computations (or equivalent)

Course Description

This unit covers analysing a simple circuit by identifying the function and operation of the circuit and circuit components contained within approved manufactured products.

Application of the unit:
This unit applies to all manufacturing environments. It covers analysis of existing circuits against specifications only and does not extend to determining modifications to circuits.
This unit does not cover the skills involved in direct measuring of values requiring connecting or disconnecting of circuits and components covered by licensing
requirements. Where such values are required they are to be obtained through the assistance of appropriately licensed personnel or through undertaking the specified training for the appropriate licence.
Work is conducted in accordance with regulatory and legislative requirements in each State and Territory.
Work is carried out under supervision

Details of Learning Activities

Learning activities will include lectures, tutorials, and laboratories.

Using workplace scenarios, participate in individual and team problem solving simulations/role plays/case studies dealing with:
• OHS procedures (including basic legal requirements; requirements for personal safety; working safely with electrical tools and equipment)
• Emergency first aid/basic life support including emergency first aid for an electric shock victim
• Rescuing from a live electrical situation
• Workshop practices in the selection, set-up and use a range of test equipment to measure voltage, current and resistance

Participate in supervised workshop practice in real and/or simulated workplace environments involving selection, set-up and use of a range of test equipment to measure voltage, current and resistance. This will include testing for continuity, insulation and identifying commonly used electrical devices in an engineering environment

The skills and knowledge described in this unit may require a license to practice in the workplace where plant and equipment is directly connected to installation wiring that operates at voltage above 50 V a.c. or 120 V d.c.

Overview of Assessment

Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor. Feedback will be provided throughout the course. Evidence of student’s competence can be gathered through a variety of ways including:
• observation of processes and procedures;
• oral and/or written questioning on required knowledge and skills;
• testimony from supervisors, colleagues, clients and/or other appropriate persons;
• inspection of the final product or outcome;
• a portfolio of documentary evidence.


Graded Assessment out of 100 Marks will be based on the results obtained for Assignments, Practical & Final Exam 
Students must gain a pass in ALL forms of assessment in order to gain this competency.



Assessment Tasks

Students are required to complete three assessment tasks as follows:

Assessment 1 - Practical (10%)

Assessment 2 - Assignment (30%)

Assessment 3 - Final Examination -Closed book (60%)
