Covers the basic theoretical and practical aspects of electrical machines and alternating current circuits. It also introduces the learner to the principles of operation of additional electronic devices and circuits. The module aim is to equip learners with the basic theoretical and practical skills required to analyse and test alternating current electrical circuits and 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.
