Subject aims expressed by acquired skills and competences
Students will learn to use electrical measuring devices, measure basic electrical quantities and passive elements.
An integral part of the student's competence is also the knowledge of calculating the deviation and uncertainty of the measurement result.
Teaching methods
Lectures
Individual consultations
Experimental work in labs
Project work
Teaching by an expert (lecture or tutorial)
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.
