Not applicable.

Students will receive a survey about problems connected with diagnostics of electrical materials and devices, about principles and organization of testing in Czech Rep. Students will be acquaint with tests which are obligatory at introducing a new electrical product to market. In practise they will be able to suggest a suitable diagnostic method for solving of a concrete diagnostic problem.

The subject knowledge on the secondary school level is required.

Not applicable.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Requirements for accreditation:
Active participation in seminars. Development, delivery and presentation of term paper.
Final written exam.
