The aim of the course is to introduce basic concepts of electrical & electronics within a context of general engineering. The topics covered are kept at an elementary level with the aim of providing the foundational material for subsequent courses at levels 1 and 2. The course adopts the philosophy of application oriented teaching. During each topic the students will be provided with examples of day-to-day devices. Topics covered include dc circuit analysis, electronic amplifiers, digital circuits, optoelectronics, and ac theory.
