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.

Way of continuous check of knowledge in the course of semester

Continuous control of the study: Continuous submission of reports and writing tests. Credit conditions: Passing tests and independent measurement. At least 25 points must be obtained together with the submission of reports. Conditions for passing the exam: The exam contains a test of 20 questions for a total of 55 points. Distance (on-line) form of study: In the distance form of study, protocols and tests are replaced by the elaboration of Theoretical Problems evaluated by 2 points, the individual measurement is replaced by a test of 25 questions by 1 point. The exam test is maintained and contains 20 questions for a total of 55 points.

E-learning

Study materials, including assignments and instructions for elaboration are available in the LMS.
