This course is the key to success for students in University or Institute and professionals in the fields of electricity. Many branches of electrical engineering, such as power, electric machines, control, electronics, communications, and instrumentation, are based on electric circuit theory. Therefore, the basic electric circuit theory course is the most important course for an electrical, electronical and IT engineering student, and always an excellent starting point for a beginning student in electrical engineering field education. Circuit theory is also valuable to students specializing in other branches of the physical sciences because circuits are a good model for the study of energy systems in general.

The entire course is valuable as it contains all the concepts DC & AC (1 and 3 Phase) circuits. With simple and easy to understand explanations and simulations, the course is more practical, dynamic, comprehensive, and presented in the following methodologies:

• Lectures with video presentations and attachments.

• High quality digital handwritten content.

• Examples, simulations and tutorials using Multisim.

• Quiz, practice tests and assignments.
