Unit description Unit description
This unit develops the fundamentals in electric and electronic circuits and the laboratory investigation and reporting. The unit covers the key electric circuit elements and their models, and analysing circuits including these models. Topics include: linear electrical components; energy dissipation, energy storage and power transfer; Kirchhoff's laws; transient versus steady-state. Linear electrical components include voltage and current sources, resistors, capacitors, and inductors. Time domain vs frequency domain circuit analysis, and impedance concept is introduced, leading to ac circuit analysis and ac power concepts.

Learning and Teaching Activities

Laboratory sessions

Practical sessions start in Week 2. They are comprised of laboratory or problem-solving workshop sessions linked to each learning outcome; and they are compulsory for all students. Students are expected to arrive on time and use the laboratory time efficiently. Students should enroll in one practical class at the beginning of the semester. Switching a practical class during semester is not possible unless a formal application of "disruption to studies" is approved. All practical sessions are based on the learning outcomes of this unit and students are required to review the concepts introduced in lectures before coming to each laboratory session. Laboratory or workshop worksheets will be posted on iLearn prior to the weekly sessions and it is compulsory for students to complete the preparatory work before coming to the session. Each student must have a bound notebook to be used as a logbook (A4 size preferred, graph pages are not required). This logbook should be used for all practical work including preliminary and post (reflection) work. It should contain dates, calculations and results recorded during these sessions, in time order. On the completion of each session, logbook entries must be signed and dated by a tutor. Logbooks must be kept in good order for a final check at the end of the semester. Food and drink are not permitted in the laboratory. Students will not be permitted to enter the laboratory without appropriate footwear. Thongs and sandals are not acceptable.
