This module provides students with the in-depth knowledge of electrical machines such as DC generators / motors, single phase and three phase AC generators / motors and transformers, which are relevant to the field of Aircraft Electrical systems. This module also covers operational amplifiers and its applications to filter circuits. The lab sessions will consist of experiments to plot generators and motors characteristic curves which will help students to reinforce their understanding of the topics covered. Students are exposed to bread-boarding, wire wrapping and soldering techniques and Printed Circuit Board (PCB) prototyping for the operational amplifier circuits. At the same time, the skills acquired from this module will provide the foundation for them to further their studies leading to a diploma.
