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.

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.

Skills and abilities
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.
