Electrical Circuits

The course gives an introduction to electrical circuit theory. It provides a fundament for understanding and designing simple circuits and systems built with analog electrical circuit elements.
Through examples and laboratory exercises the students should achieve a practical knowledge of analog electronic circuit elements, exercise in use of basic laboratory equipment and an introduction to writing laboratory reports.
Topics covered include: Conventions and elements in electrical circuits, Ohm's and Kirchhoff's laws, simple resistive circuits, techniques of circuit analysis, capacitance and inductance, first-order RC and RL circuits (natural and step response), photovoltaic cells, power system, diodes, thyristors, DC machine, super conductors and smart grids.

Knowledge: After finishing the course, a student should be able to:
- understand the basic theory and mathematical relationships in circuit analysis
- understand basic terms and results from the theory about circuits with resistances, capacitances and inductance components, as well as basic semiconductor components
- know the principles for ideal circuits and power grid components
- solve problems using simple solar cell models.
Skills: After finishing the course, a student should
- be able to use basic circuit theory to solve problems in electrical engineering and analyze/design simple circuits
- be able to use laboratory equipment such as voltmeter, ammeter, oscilloscope and signal generator
- be able to describe the most important components and functioning of the power distribution network
- have knowledge about the energy production using, e.g., solar cells, and basic DC motors/generators

Lectures, mandatory theory- and laboratory-exercises.
