## Learning Outcomes

The student becomes familiar with basic phenomena and quantities in electrical engineering. The student learns how to calculate DC circuits and can apply the learnt methods to calculate phenomena, which occur in DC circuits.

54 h, which contains 28 h of scheduled contact studies.
The assessment of student’s own learning 1 h is included in contact lessons.

## Contents

Quantities related to DC circuits such as electric charge, voltage, current, resistance, power and energy. Basic laws controlling the behaviour of DC circuits such as Ohm's law, Kirchoff's law and Joules'a law. Various resistance couplings (serial, parallel, star and delta couplings) and their reduction. Sources of power, their characteristics, definition of components for a equivalent circuits. DC circuits couplings and the most important solutions. Arrangements of resistors in DC circuits (serial arrangement and potentiometre adjustment).

## Recommended or Required Reading and Other Learning Resources/Tools

Material delivered by the teacher.

## Mode of Delivery / Planned Learning Activities and Teaching Methods

Electrotechnical theory related to DC circuits and how to apply it in practice is studied during lectures. Then the students independently apply what they have learnt by doing practically oriented exercises. The correct solutions to the exercises are shown during the demonstrations.

## Assessment Criteria

Grade 5: The student is able to apply creatively the contents of the course.
Grade 3: The student is well-abled to utilize the course contents.
Grade 1: The student knows those subjects of the course, which are necessary for the forthcoming studies and working life.

## Assessment Methods

An examination and activity in exercises.
