Intended learning outcomes

Electricity as a power source and information carrier is necessary for our modern society to function. The course treats the basics of these electrical systems, both theoretically and practically. The basic electronic components are treated as well as how measurements of non-electrical quantities can be made through electrical methods. The course will give the knowledge to understand and deal with electrical and electronic problems at home and in industry. Therefore the student should be able to:

  • Make calculations on DC- and AC-circuits.
  • Understand the function and make easier calculations at electromagnetic connections.
  • Use structured methods for analysis and construction of electronic circuits.
  • Make measurements on electrical quantities as voltage, current, power etc.
  • Chose suitable sensors and measuring methods to (in an electrical way) measure non-electrical quantities like speed of revolution, force, temperature, pressure etc.

Course content

  • Direct current and alternating current.
  • Voltage, current and power.
  • Ohm’s law and electric resistance.
  • Serial and parallel connection.
  • D/Y- and Y/D-transformation.
  • Kirchhoff’s laws.
  • Superposition. Thévenin’s and Norton’s theorem.
  • Mesh current and node voltage method.
  • Sinusodial alternating current, phasor diagram and the complex methode.
  • Power in alternating current circuits .
  • Magnetism and the ideal transformer.
  • Transients treated with the Laplace transform.
  • The diode and the Zener diode.
  • Rectifying and smoothing.
  • The transistor and its operating point.
  • Small signa lmodels and basic amplifier stages.
  • The Operational amplifier.
  • Frequency dependence and Bode plots.
  • How to use electricity for measuring non-electrical quantities like with laborations on air flow, temperature, pressure in an heat exchanger and measurements of time, frequency, speed of revolution, force and vibration.

Regulations (apply to LiU in its entirety)

The university is a government agency whose operations are regulated by legislation and ordinances, which include the Higher Education Act and the Higher Education Ordinance. In addition to legislation and ordinances, operations are subject to several policy documents. The Linköping University rule book collects currently valid decisions of a regulatory nature taken by the university board, the vice-chancellor and faculty/department boards.

LiU’s rule book for education at first-cycle and second-cycle levels is available at http://styrdokument.liu.se/Regelsamling/Innehall/Utbildning_pa_grund-_och_avancerad_niva.
