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.

Lectures – 33 hours
Tutorials – 5 hours
Laboratory – 8 hours
Information on contact teaching time is available from the course guide.
1st Attempt: One written examination of two-hours duration (80%) and continuous assessment based on the 4 laboratory/design exercises (20%).
Students will have their log book and lab reports assessed on several occasions during the half session, and these will be returned to them with markers' comments. There will also be opportunities for informal formative assessment and feedback in the weekly tutorial sessions.
a) Students can receive feedback on their progress with the Course on request at the bi-weekly tutorial/feedback sessions or by making appointments to see the course coordinator.
b) Students requesting feedback on their exam performance should make an appointment with the course coordinator within 2 weeks of the publication of the exam results.
c) Students can obtain feedback on their understanding of key aspects of the course through self-administered MyAberdeen quizzes or through example questions during lectures.
