• Course level: Beginner



This subject is commonly known as Network theory, Electrical circuit, Network analysis, circuit theory.

This course explains how to analyze circuits that have direct current (DC) current or voltage sources. A DC source is one that is constant. Circuits with resistors, capacitors, and inductors are covered. Network theorem is covered.

After completing this course, you will be able to solve any DC circuit easily. I have explained each and everything with solved examples.
