(3 hours) Specific assessment methods/tasks Total Upon satisfactory completion of the subject, the students are expected to: 1. Lectures are the primary means of conveying the fundamental knowledge to understand the concepts pertaining to the fundamental aspects of electrical and electronic principles. Tutorials with problem-based questions are given, and the students are expected to solve those problems and to know the basic approaches to solving the problems. Students will be required to form groups to work on laboratories which will give them a hands-on experience in the devices, circuits and machines that are taught in the lectures.
