Learning Outcomes



Details of Learning Activities

This unit covers determining correct operation of electromagnetic circuits and providing solutions as they apply to electrical installations and equipment. It encompasses working safely, power circuit problems solving processes, including the use of voltage, current and resistance measuring devices, providing solutions derived from measurements and calculations to predictable problems in multiple path circuit.

Classroom tutorial activities: to consolidate the concepts of electromagnetism, and electromagnetic applications. This includes calculations for electromagnetic quantities, voltage generation, motor torque, efficiency and power calculation.

Following topics will be covered: magnetism, electromagnetism, magnetic units, magnetization curve, electromagnetic induction, Inductance, Electromagnetic applications, relays, contactors, rotating machines, generators, motors, DC series, shunt and compound motors, motor loads, speed torque characteristics,

Practical exercises: to demonstrate an understanding topics related electromagnetic quantities, inductors, transients and transformers

Work simulated activities: to construct of DC motor control starting, reversing and braking circuits.


It is expected that students will require approximately 20% of course hours to be allocated for independent study to do project research, design, construction, testing and problem solving activities.
