Description
The course has been explained in a practical manner, relying on simplicity in theoretical explanations and placing greater emphasis on visuals and real-life practical examples. This approach allows us to connect academic theoretical study with what actually exists in practical reality for real-world application after completing this course.

The course we have is closely related to the power systems and electrical distribution systems. In this course, we provide the following:
