On the basis of
The course builds on these mathematical topics: Complex numbers, differentiation, integration, 1st and 2.order differential equations, linear equations in matrix form. The course builds on classical mechanics and especially subject of statics. Physics for Yway and TRES must be taught before or in parallel with this course. The basis is Newton 1., 2. and 3. law, and those in vector form. Energy and power. Potential and kinetic energy. Electrostatics and electromagnetism are added towards the end of the topic Electrical circuits.

Problem solving
The course is based largely on laboratory work that is practical application of lectured material. Students work on constructing electrical circuits, then assemble them and conduct measurements on them to verify if they work as intended.
The Flex Students (flexible race) must come to campus twice for two days to conduct the laboratory exercises.
Form(s) of Assessment
Written exam, 3 hours
Written exam, 5 hours
Form(s) of Assessment (additional text)
Written Exam for the Electrical Circuit part, 5 hours (counts 75%)
Written Exam for the Physics part, 3 hours (counts 25%)
Each exam must be passed.
Grading Scale
Alphabetical Scale, A(best) – F (fail)
External/internal examiner
Internal examiners do the evaluation and grading of the exams. Next time an external examiner will be used is in 2017
Resit examination
Ordinary resit exams. If the student fails on only one of the two exams in the course, the student are not required to take resit exams for both parts of the course. The student only need to take resit exam for the part the student has failed to pass.
If the student take resit exams for both parts of the course and only passes one of part in the resit exam, the passed part of the resit exam will count. At the next exam the student then only need to take the part where it failed on the resit exam.
Examination support
Alternative C: Certain specified written aids and simple calculator (on approved list) are allowed for the exam.
Coursework Requirements
There are 12 to 15 exercises in the course. 3 of the exercises in the fall semester and 4 of the exercises in the spring semester must be submitted according to given deadlines. Approval of these must be given to be allowed to take the exams.
All laboratory exercises are mandatory. It is also mandatory to write and submit a lab journal for all labaratory exercises. In addition 2 laboratory report must be submitted according to given deadlines. Approval of these must be given to be allowed to take the exams.

Additional information
The course is the basis course for all courses within Electrical engineering. For students within renewable energy the course is important to understand integration of renwable energy and to choose courses that relates to integration of renwable energy in the electrical power system. Alternatively choose courses that gives insight in conversion of different forms of energy to electrical energy.
For applications for the accreditation , transfer and recognition of courses from earlier years or other institutions, each application is treated individually and applicants must be prepared for credits reduction in cases of overlapping topics.
The electric circuit part is equivalent to 15 ECTS Credits and the physics part is equivalent to 5 ECTS Credits.
