Syllabus: Network Theory (Electric Circuits) GATE EE - Electrical Engineering (EE) PDF Download

Network theory is the study of solving the problems of electric circuits or electric networks. It is the most important subject for any Electrical Engineering or Electronics & Communication Aspirants. At the same time, it’s a prerequisite for other important subjects such as Analog Electronics, Electrical Machines, Power Systems, etc.

The problems are not so tricky in this subject and it becomes one of the better scoring topics in the GATE examination. It’s advisable you should avoid mistakes, learn every topic carefully as it will majorly impact your GATE score. The weightage of Network Analysis will mostly be anywhere between 8 to 12 marks in the GATE 2023 for both the streams i.e. EE and ECE.

In this document, we will discuss the syllabus for Network Theory in detail and also providing the entire content through which you can start and strengthen your preparation.
