Circuits and Measurements

Valid for: 2014/15

Decided by: Education Board A

Date of Decision: 2014-04-07

Compulsory for: IDA1, IEA1

Language of instruction: The course will be given in Swedish

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.

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.

*Part dc circuits:*

- Current, voltage and resistance
- Resistor and potentiometer. Colour code
- Ohm's Law and Kirchhow's laws
- Thevénin and Norton equivalent circuits
- Superposition
- Power in dc circuits
- The ideal operational amplifier
- Capacitor and induktor

*Part ac circuits*:

- Sinusoidal time dependency: The phasor diagram, complex method, impedance and admittance, apparent power, avarage power, reactive power
- Direct and alternating current/voltage measurements: measurement of voltage, current and resistance with the aid of the analogue and digital multimeter. Oscilloskope.The influence of the measurement instrument
- Average value, average absolute value and the effective value (RMS) of periodical signals
- The ideal transformer

Grading scale: TH

Assessment: Grad 3: passed written examinations, passed laboratory preparation reports, passed laboratory experiments and one passed laboratory experiment report. Higher grad through the written examinations. Final grade = interger of (3,5 x grade part 1 + 4 x grade part 2) / 7,5, but not more than 5,0.
