Learning Outcomes

The student becomes familiar with the basic phenomena and quantities of electrical engineering both in DC and AC circuits. The student learns the basic calculation methods and knows how to apply learned methods in the calculation of simple circuits.

Student's Workload

The total amount of student's work is 81 h, which contains 42 h of contact studies in the youth program and 30 h of contact studies in the adult program. The remaining time is used for individual studies.
The assessment of student’s own learning 1 h is included in contact lessons.

Prerequisites / Recommended Optional Courses
