Introduction:
Electrical Engineering (EE) is a branch of engineering that deals with the study and application of electricity, electronics, and electromagnetism. It is a vast field that encompasses various areas such as power generation, transmission, distribution, control systems, electronics, telecommunications, and many more. One of the most popular exams for students pursuing a career in EE is the Graduate Aptitude Test in Engineering (GATE). In this article, we will discuss how to prepare for the GATE Electrical Engineering (EE) exam.
