The research is all about the Engineering Services Exam Syllabus for Electrical Engineering 2018.

As we all know about IES exam, now the name of IES has been changed to ESE means Engineering Services Examination is conducted by UPSC for recruitment in a variety of engineering services  in various Government Departments . The enrollment mainly takes place for three categories they are Electrical Engineering and Electronics & Telecommunication Engineering , Mechanical Engineering  and  Civil Engineering. Indian Engineering Services are the civil services that meet the technical and executive functions of the Government of India. The Government of India enrolls its civil servants as well as officials on the basis of merits  filled through competitive exams. Large number of candidates take these exam every year willingly  competing for limited posts. IES officers are selected by the union government on the recommendations made by the UPSC.

Electrical Engineering is a field of designing that for the most part manages the study and use of power, hardware, and electromagnetism. This field first turned into an identifiable occupation in the recent a large portion of the nineteenth century after commercialization of the electric broadcast, the phone, and electric force appropriation and utilization. Therefore, TV and recording media made gadgets a piece of every day life. The innovation of the transistor and, in this manner, the coordinated circuit cut down the expense of gadgets to the point where they can be utilized as a part of any family unit object.
