| Summary |
|---|
Students will learn to use all types of measuring devices, from analog to digital to virtual, which they will also try to create. They will be able to measure basic electrical quantities and passive elements using various methods.
An integral part of every measurement is also knowledge of the calculation of deviation (error), the uncertainty of the measurement result.

| Learning Outcomes of the Course Unit |
|---|
Students learn to use electrical measuring instruments and to measure basic electrical quantities.
An integral part of the student's competence is also the knowledge of calculating the deviation and uncertainty of the measurement result. |
