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 Y-way 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.

Replacement course for
ELE1042 Elektriske kretser
The course has the same themes as ELE1042 Elektriske kretser. However, it is taught over two semesters and not one semester like ELE1042 Elektriske kretser.
