Circuits and Measurements
ETE604, 7,5 credits, G1 (First Cycle)
Valid for: 2013/14
Decided by: Education Board A
Date of Decision: 2013-04-15
General Information
Compulsory for: IDA1, IEA1
Language of instruction: The course will be given in Swedish
Aim
The aim of this course is to give the students the basic
knowledge about electric components and circuits. Solving problems
and the laboratory works are often shown to be the results of real
inventions and the answers to real needs in industry, the office
and the home.
Learning outcomes
Knowledge and understanding
For a passing grade the student must
- be able to explain and use the basic electric quantities:
current, voltage, resistance, impedance and power in a given
electric circuit using the theoretical models described in this
course
- be able to refer alternating current and voltage phasor
diagram into the complex plane
- be able to present a report of a planned and executed
measurement in an electric circuit.
Competences and skills
For a passing grade the student must
- be able to calculate currents, voltages, reactances, impedances
and power in a given electric circuit using the theoretical models
described in this course
- be able to plan and execute measurements electric quantities
in an electric circuit
- be able to analyse and explain the function and properties of a
given electric circuit
- be able to explain the function of a resistor, capacitor,
inductor, ideal operational amplifier and ideal transformer working
in an electrical ac or dc circuit.
