# Krets- och mätteknik 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.
