Task Instructions

Summary and Purpose of Assessment:

There are total two assignments under Assessment 2 and this is Assignment 1.

This assessment covers determining correct operation of complex multiple path circuits and providing engineering solutions as they apply to various branches of electrotechnology work functions. It encompasses working safely, problem solving procedures, including using electrical measuring devices, applying appropriate circuit theorems and providing solutions derived from measurements and calculations and justification for such solutions

Assessment Instructions

You must demonstrate an understanding of:

· Prepare to solve problems in complex multiple path circuits by understanding various OHS procedures, obtaining advise and documentation from supervisor, and sourcing various equipment’s, tools and testing devices according to established procedure.

· Solve problems in complex multiple path circuits in accordance with OHS Requirements and procedures and circuit problem solving methodologies in a safe and Sustainable execution.

· Complete work and document problem solving activities by cleaning the work site and proper justification of solutions through documentation.

What and where: This is an individual based assignment to be completed outside classroom.

How: Students will be assessed according to the criteria outlined in the Criteria for Assessment below. All criteria identified must be addressed to satisfactorily complete this Assessment Task.

Additional Instructions for Students:

1. Attempt ALL the questions/tasks in each assignment.

2. Performance requirement for each assignment:

a. Satisfactory (S) performance- complete all the questions/tasks correctly

b. Not Yet Satisfactory (NYS) performance – unable to complete all the questions/tasks correctly

3. You need to achieve satisfactory (S) results in both assignments to gain satisfactory (S) in assessment 2.

4. You need to achieve satisfactory (S) results in all three (3) assessments to be deemed Competent (CA).

Conditions for assessment

Instructions to students:

· All answers are to be written in blue or black pen only, excluding diagrams, or the answers will not be marked (Written tests only).

· The ONLY materials, equipment or personal items which may be brought into the test room are blue or black pens, pencil, eraser and correction fluid (unless otherwise permitted by invigilator)

· There is to be NO communication of any kind with any other person either inside or outside the tests venue, except with the test supervisor/invigilator or course teachers.

· Test papers and other material provided by the University are NOT to be removed from the test room.

· You are not permitted to return to the test room, if you leave without permission from the invigilator.

· You must be observed undertaking this assessment task by a qualified assessor

· You can negotiate a suitable time and location for assessment at least one week prior to the assessment taking place

· You can make arrangements with the assessor at least one week prior to the assessment due date if you require special allowance or allowable adjustment to this task.

· If you are found in breach of assessment conditions you can be charged with academic misconduct, and have your results cancelled, be excluded from the program and receive other penalties. Penalties can also apply if your test material is copied by others.

· Plagiarism is the presentation of the work, idea or creation of another person as though it is one’s own. It is a form of cheating and is a very serious academic offence that may lead to expulsion from the University. Plagiarised material can be drawn from, and presented in, written, graphic and visual form, including electronic data, and oral presentations. Plagiarism occurs when the origin of the material used is not appropriately cited.

· RMIT special consideration is to enable you to maintain your academic progress despite adverse circumstances. The process for special consideration can be found at http://www1.rmit.edu.au/students/specialconsideration

· If you have a disability or long-term medical or mental health condition, you can apply for adjustments to your study and assessment conditions (Reasonable Adjustments and Equitable Assessment Arrangements) by registering with the Equitable Learning Services (ELS) at https://www.rmit.edu.au/students/support-and-facilities/student-support/equitable-learning-services

· If you are already registered with ELS and your study plan is approved, please inform the teacher if this assessment task is not adjusted in line with approved study plan.

· You will be assessed as satisfactory or not yet satisfactory.

· You can appeal the assessment decision according to the RMIT Assessment Appeal Processes

· You have to undertake research activity to complete this assignment.
