Laboratory work

  1. Full wave rectifier
  2. Voltage stabilizer
  3. Peak and mean voltage detectors
  4. Switching mode power supply

Applications to exams

Dates and applications to the exams

Exam dates are announced in STUDIS, where it is also necessary to register. If you have trouble applying, contact the Student office.

  • Requirement for the written exam: All laboratory exercises completed*
  • Requirement for the oral exam: Pozitivno ocenjen pisni izpit (at least 50 out of 100 points)

*Exercises completed in at least the previous two academic years are also taken into account.

Permitted aids in the written examin

  • A4 sheet of equations compiled by the student himself. The sheet should not contain schemes or solved tasks.
  • Dedicated calculator (mobile phones and tablets not allowed)

Exam solutions

Exam solutions will be available in the e-classroom shortly after the written exam.

Exam results

Written exam grades will be available at STUDIS, usually the next business day after the exam. You will be notified when they are entered. The graded exams can be viewed in the Glažar - BN312 office.
