This is a foundation course in electrical and electronic systems for first year learners of Automation Engineering. It covers the basic theoretical and practical aspects of electricity, magnetism and direct current electric circuits. It also introduces the learner to the basic principles of operation of digital electronic circuits. The module aim is to equip learners with the basic theoretical and practical skills required to analyse and test low voltage direct current electrical and small signal electronic circuits, while also equipping them with the foundation skills required for further studies in the areas such as electrical systems, electronic systems, electronics and instrumentation.
