If you are preparing for UPSC ESE 2027, understanding the ESE Electrical Syllabus is the first step towards a solid study plan. UPSC Engineering Services Examination (ESE), also called IES, is one of the most respected exams for engineering graduates in India.
This article covers the complete ESE electrical engineering syllabus for Prelims and Mains, along with exam pattern, marks distribution and best books.
UPSC ESE 2027 Exam Pattern: Quick Overview
Before going into the UPSC ESE Electrical Engineering Syllabus, let us see how the selection process works. ESE 2027 has three stages- Prelims, Mains and Personality Test (Interview).
| Stage | Exam | Maximum Marks |
| Stage I | Preliminary | 500 |
| Stage II | Mains | 600 |
| Stage III | Personality Test | 200 |
| Total | Grand Total | 1300 |
ESE Prelims Electrical Syllabus
The ESE Prelims Electrical Syllabus has two objective-type papers held on the same day. Let us see the ESE Prelims Electrical Mark distribution given below:
| Paper | Subject | Duration | Marks |
| Paper I | General Studies and Engineering Aptitude | 2 hours | 200 |
| Paper II | Electrical Engineering (Technical) | 3 hours | 300 |
| Total | 5 hours | 500 | |
Paper I is common for all branches and covers current affairs, reasoning, engineering mathematics and ethics.
Paper II is the core technical paper, and this is where the ESE syllabus for electrical engineering becomes important. It tests fundamentals from entire degree, so a good ESE Prelims Electrical book covering objective-type problems is essential for this stage.
ESE Electrical Mains Syllabus
Once you clear Prelims, you move to Mains. This part of the ESE Electrical Engineering Syllabus is descriptive in nature.
| Paper | Subject | Duration | Marks |
| Paper I | Electrical Engineering Paper I | 3 hours | 300 |
| Paper II | Electrical Engineering Paper II | 3 hours | 300 |
| Total | 6 hours | 600 | |
Each Mains Paper has around 8 descriptive questions and candidates must attempt a set number correctly. Conceptual clarity and neat presentation matter a lot here.
Detailed ESE Electrical Syllabus: Topic-Wise Breakdown
Let us see the detailed ESE Electrical Engineering Syllabus as per the official UPSC Pattern given below:
Paper I Topics
| Subject | Key Areas |
| Engineering Mathematics | Matrix Theory, Eigen values, differential equations, complex variables, probability & statistics |
| Electrical Materials | Insulating, magnetic and semiconductor materials, nano materials, superconductors |
| Electric Circuits and Fields | KCL, KVL, network theorems, three-phase circuits, Maxwell’s equations |
| Electrical & Electronic Measurements | Bridges, Instruments, transducers, sensors, error analysis |
| Computer Fundamentals | Number Systems, Boolean Algebra, CPU architecture, operating systems |
| Basic Electronics Engineering | Diodes, transistors, amplifiers, oscillators |
Paper II Topics
| Subject | Key Areas |
| Analog & Digital Electronics | Op-amps, logic circuits, microprocessors, A/D- D/A converters |
| Systems and Signal Processing | Fourier and Laplace transforms, Z transform, FIR/IIR filters |
| Control Systems | Transfer functions, Bode plots, root locus, state-space model |
| Electrical Machines | Transformers, DC Machines, induction and synchronous machines |
| Power Systems | Generation, transmission, fault analysis, protection, smart grid |
