Teaching Method

Outline:

We lecture on the theory and characteristics of transformers and induction machines which are often used in electrical equipment and others.
Teaching materials and home-work learning materials are provided by the e-learning system.
Since this class is an essential subject of the national examination of electric chief engineers, we provide information to take the qualification examination.

Style:

Classes consist of lectures and home learning using e-learning learning materials.

Notice:

The lesson plans may be changed according to the degree of understanding of students.
It is necessary for students to understand the contents of electric circuits and electromagnetism in advance.
