Network analysis is a structured technique used to mathematically analyze a circuit. Most electrical networks are very complex. To analyze them, circuit theorems, techniques and laws are really important. Superposition Theorem, Thevenin Theorem, Norton Theorem, Maximum Power Transfer Theorem, Substitution Theorem, Millman Theorem and Reciprocity Theorem are the fundamental laws used for network analysis. All these circuit theorems help us to find the basic electrical parameters like voltage and current in a simpler way.

This course is designed to help students to understand the fundamentals of network analysis including three phase systems, reactive power compensation and filters.

After completing this course, students will have fundamental knowledge on the network techniques, like node analysis and loop analysis, to write equations for large linear circuits.
