Course content

The course provides basic knowledge of circuit analysis for linear physical energy systems. Analysis and measurement of electrical energy circuits is the main focus of the course, but the circuit concept and analysis techniques will also be applicable to other physical domains. The course covers DC circuits, introduces AC signals and simple rectifiers.

Items in the subject:

• Direct current and voltage, resistance, power and energy.
• Component characteristics of as well as circuits with voltage sources, current sources, resistance, inductance, capacitance, switches/diodes, ideal operational amplifier and ground.
• Ohm's law and Kirchhoff 's law current law and voltage law .
• Different methods of linear circuit analysis; for example source transformation, circuit simplifications, node analysis , loop analysis, superposition, as well as Thevenin and Norton equivalent.
• Transient analysis (turn-on and turn-off) in RL, RC and RLC circuits
• Analogies to, as well as application of, the circuit concept and analysis techniques to other physical domains.
• Introduction to alternating current and voltage (AC signals)
• Basic power electronics and non-linear systems: rectifiers and DC converters.
• Reflections on ethics and sustainability in connection with electrical systems and components.
• Brief description of the historical development within circuit theory.
• Hand calculation and simulation/calculation using digital tools.
• Group work, laboratory work and documentation of this.

Some adjustments to the theme and focus may occur, and more detailed information about the syllabus will be made available at the start of the semester.

Learning outcome

The student must understand:

• The basic characteristics of a selection of electrical circuits and understand how electrical circuits can be controlled.
• Understand how the circuit concept can be transferred to other physical domains.
• Safety in the lab, physical circuit connections and troubleshooting, as well as precision and limitations in measuring instruments.

The student must be able to:

• Use network theorems, component characteristics and fundamental laws in electrical circuit theory to calculate parameters in systems with a selection of components.
• Carry out system analyzes using hand calculations and simulations, as well as practical connection and measurement in the lab.
• Connect simple circuits according to given specifications. Measure electrical values using a multimeter and oscilloscope.
• Use various circuit components to create circuits with desired properties.
