·         Charge, voltage, current, power, and energy.

• Direct and alternating current.
• Ohm’s law and Kirchhoff’s laws. Series and parallel circuits.
• Knowledge of components (R, L, C) and ideal transformer.
• Phasor notation. Mathematical operations with complex numbers.
• Frequency and amplitude functions for linear systems
• Superposition, Thévenin’s Theorem, Norton’s Theorem and Nodal analysis.
• R-C and R-L circuits and response circuits
• Electric and magnetic fields.
• Diode, rectifying, zener diode and power supply
• An overview on symmetrical three phase systems

After completion of the course the student should be able to:

• Explain the basic electrical and magnetic concepts.
• Descibe passive components and electrical networks.
• Perform network calculation and simulation.
• Analyze basic circuits.
• Dimension circuits using passive components
• Measure electrical circuits

Physics 2, Chemistry 1, Mathematics 3c. In each of the subjects, a minimum of the grade E is required.

The course litterature will be given four weeks before the course start, and will be announced in the course PM.

If the course is discontinued, students may request to be examined during the following two academic years.

• LAB1 - Laboratory Work, 2.0 credits, grading scale: P, F
• TEN1 - Examination, 5.0 credits, grading scale: A, B, C, D, E, FX, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.
