18

Read the complete UPSC CSE Mains Electrical Engineering syllabus for paper 1 and 2 in English. This article will tell you about the topics/chapters of Electrical Engineering that comes under the syllabus for the UPSC IAS mains exams. UPSC CSE (Civil Services Exam) is commonly known as the IAS exam. The Mains Optional subject Electrical Engineering is one of the subjects from those a good amount of questions comes in the UPSC CSE Prelims exam too. So it is very important to study deeply.
