Course information

Content and learning outcomes

Course contents *

1. Basic components, voltage and current sources (independent and dependent). Ohm's law and Kirchhoff's laws. Analytical methods including nodal analysis, mesh and loop analyses, superposition and graphical methods.
2. Two pole equivalents (Thevenin and Norton equivalents).
3. Operational amplifiers.
4. Transient switching including equilibrium and continuity. Time dependent quantities in dynamic circuits.
5. Complex numbers. Alternating current and time harmonic signals analysed with the complex method (the j omega-method). Impedances.
6. Complex power. Active, reactive and apparent power. The Tellegen theorem. Matching, phase compensation and power factor.
7. Inductive coupling and transformers.
8. Filter circuits and Bode diagrams/plots.
9. Three-phase systems and balance in such systems.
10. Applications. The course CDIO-elements include dimensional analysis and to design, dimension and create basic circuits, under the concept ”Conceiving”, with introductory elements of ”Designing”.

Intended learning outcomes *

After completing the course with a passing grade the student should be able to:
• apply theories and methods in circuit analysis, and reproduce basic theorems and definitions of important concepts that are described in the course content
• solve parts of problems from the major part of the course content by setting up a calculation model and solve the problem analytically choose appropriate method; make proper approximations; formulate and solve necessary equations; evaluate the result in order to solve for quantities in linear electric circuits.
For higher grades, the student shall in addition be able to with progression in both completeness and scope, solve problems from the whole course content.

Course Disposition

The course consists of lectures, exercises and laboratory sessions. For participation you must register to the course. The course is a problem solving course that requires you independently solve a lot of assignments. You shall yourself choose a suitable solution method and carry out the calculations that the solution method gives origin to.

Literature and preparations

Specific prerequisites *

Upper Secondary School mathematics and physics/technology as well as the courses in mathematics for CELTE1 at KTH or the equivalent.

Basic concepts: current, potential, voltage, resistance, power. Ohm's law, Kirchhoff's laws. Linear differential equations with constant coefficients. Complex numbers. polar and Cartesian representations, algebraic operations, complex conjugate.

From experience we know that many have forgotten their previous knowledge in electric circuits, wherefore we have prepared a binder with repetition material containing examples from DC-circuits where one should apply the laws of Ohm and Kirchhoff.

Recommended prerequisites

Gymnasiematematik och -fysik/teknologi samt kursen i matematik för E1 vid KTH eller motsvarande.

Väl inhämtade kunskaper om komplexa tal, algebraisk bråkräkning med komplexa storheter, polär och kartesisk form för polära tal samt Eulers formel används flitigt. Vidare förväntas studenten känna till spänning, ström, effekt, serie och parallellkoppling av resistanser.

Examination and completion

Grading scale *

A, B, C, D, E, FX, F

Examination *

  • LAB1 - Laboration 1, 1.0 credits, Grading scale: P, F
  • LAB2 - Laboration 2, 1.0 credits, Grading scale: P, 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.

In agreement with KTH´s coordinator for disabilities, it is the examiner who decides to adapt an examination for students in possess of a valid medical certificate.. The examiner may permit other examination forms at the re-examination of few students

Ethical approach *

  • All members of a group are responsible for the group's work.
  • In any assessment, every student shall honestly disclose any help received and sources used.
  • In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
