Electrical Engineering 1

This is the study programme for 2019/2020. It is subject to change.


The objectives of this course are to give the students an introduction to fundamental subjects in electrical engineering.

Learning outcome

Knowledge:
By the end of the course, a successful student should:
- Have a basic knowledge of electric circuits and parameters,
- Be able to do computations on electric circuits,
- Be able to do computations of energy and power for single phase and three-phase systems.
- Perform computations on circuits with diodes (also zener diodes) such as regulators and rectifiers.
- Perform computations on power electronic circuits.
- Be able to do computations on magnetic circuits (transformers and electric machines).
Skills:
The result of the studies should be that the student has acquired skills in design and analysis of some chosen electronic and electromagnetic circuits.

Coursework requirements

Approved laboratory exercises, Godkjente regneøvinger
Compulsory laboratory exercises: 8 Compulsory hand-in assignments: 5
Completion of mandatory lab assignments are to be made at the times and in the groups that are assigned and published. Absence due to illness or for other reasons must be communicated as soon as possible to the laboratory personnel. One cannot expect that provisions for completion of the lab assignments at other times are made unless prior arrangements with the laboratory personnel have been agreed upon.
Failure to complete the assignments on time or not having them approved will result in barring from taking the exam of the course.

Method of work

Weekly 4 hours lecturing, 2 hours guided problem-solving and 2 hours laboratory work through the semester. Each lab exercise consist of a theoretical pre-lab and 3 hours LAB work. The pre-lab has to be carried out before the work in the LAB can start. Mandatory work demands (such as hand in assignments, lab- assignments, projects, etc) must be approved by subject teacher three weeks ahead of examination date.
