Assigned Department Objectives

Teaching Method

Outline:
The students will master DC circuits based on the knowledge of electricity learned at junior high school. In this course, the target is to be able to calculate the electric current, voltage, power etc. in circuits. DC circuits are not only the foundation of AC circuits to be learned in the future, but also the basis of electric / electronic circuits and an important theme.
Style:
In this course, the lectures and exercises will be conducted using supplementary materials and texts. To master electrical circuit, it is essential that the students solve problems, solving problems leads to a better understanding. Therefore, before the end of class, quizzes and task reports will be conducted to ensure students knowledge acquirement.
Notice:
The content of this course is of 90 hours, and it includes self-learning time. The students should strictly respect the deadline of the assignments. ( up to 5 absences are excused )
