GATE EE (Electrical Engineering) for 2027 has ten syllabus sections. Of the 100 marks, 15 are General Aptitude, 13 are Engineering Mathematics and 72 are for the nine EE subjects, with Electrical Machines, Power Systems, Control Systems and Electric Circuits the largest blocks in recent papers. IIT Madras revised every GATE syllabus for 2027, the first revision since 2021. Begin with Electric Circuits, because Machines, Control, Power Systems and Electronics all use its methods.

How GATE EE marks are divided

PartMarks
General Aptitude15
Engineering Mathematics13
EE subjects (sections 2 to 10)72
Total100 (65 questions, 3 hours)

The common rules on MCQ, MSQ and NAT questions and negative marking are in the GATE exam pattern. For scale, 81,947 candidates registered for EE in GATE 2026, 65,801 appeared and the General-category qualifying mark was 27.7 (official IIT Guwahati table). It is an illustration only, because each year's mark is computed after the exam.

The GATE 2027 EE syllabus, section by section

A topic-by-topic comparison with earlier syllabi has not been made here, so do not assume which topics are new. Use the official EE syllabus PDF as your checklist.

What deserves the most time

GATE publishes no topic weightage, and the syllabus revision makes older patterns a weaker guide. In recent papers, Electrical Machines, Power Systems, Control Systems and Electric Circuits have been the larger blocks, with Analog and Digital Electronics and Power Electronics in the middle and Measurements, Electromagnetic Fields and Signals and Systems smaller. This is an unofficial reading of past papers, not a rule.

Three practical points follow from the syllabus itself:

  • Machines and Power Systems are long and numerical. The syllabus lists many sub-topics for each. Make summary sheets of per-unit conversions, equivalent circuits and fault formulas, and practise numericals daily.
  • Four subjects have close counterparts in GATE EC. Circuits, Signals and Systems, Control Systems and Analog and Digital Electronics overlap with EC's Networks, Signals and Systems, Control Systems, Analog Circuits and Digital Circuits, which matters if you plan a second paper.
  • The maths block has Fourier series and vector calculus, which come back in Signals, Electromagnetic Fields and Circuits. Revise them early; the Engineering Mathematics guide has the shared topics.

The order to study

  1. Electric Circuits. Network theorems, transients, resonance and three-phase circuits are the base.
  2. Engineering Mathematics, in short blocks alongside circuits: linear algebra and differential equations first.
  3. Signals and Systems, then Control Systems. Both use Laplace transforms.
  4. Electromagnetic Fields. It supports transformers, machines and transmission lines.
  5. Electrical Machines. Transformers first, then DC, induction and synchronous machines.
  6. Power Systems. Needs circuits, per-unit values and machines.
  7. Analog and Digital Electronics, then Power Electronics.
  8. Measurements. Short and descriptive; finish it in a week.

Books commonly used for GATE EE

A 21-week first pass, then mocks

22-26Topic-wise past-paper sets, then full-length mocks on the virtual calculator

Machines and Power Systems questions are calculation-heavy, so practise the numericals on the on-screen scientific calculator, the only calculator allowed in the exam. Keep 15 minutes a day for General Aptitude from the start. Where to find official papers is in the previous year papers guide.

Pairing EE with a second paper, and what happens next

EE can be paired with DA, EC, IN, PH or RA. EE plus EC is a popular pair, and the overlap in circuits, signals, control and electronics is large; read the GATE ECE guide to see the other side. EE and CS cannot be combined. Both papers go in one application.

In GATE 2026, EE was named by EIL, GAIL, OPTCL, NPCIL and POWERGRID in their recruitment announcements. POWERGRID's Engineer Trainee 2027 advert, issued on 24 September 2026, lists Electrical, with an upper age limit of 28 as on 31 March 2027 and a minimum of 60% in the degree. PSUs set their own age limits and minimum marks even though GATE has no age limit, and they change every cycle. The after GATE guide explains the PSU and M.Tech routes. The full exam is in the GATE hub.

Practising GATE EE with PrepMatic

PrepMatic's free GATE assessment is about 15 multiple-choice questions, untimed, and shows your weakest and strongest subjects with a projected score out of the paper's maximum. Because EE has ten sections, the subject-level view tells you which to start with. You get a study plan built from your exam date, daily hours and study days, plus topic tests and custom mocks focused on your weak subjects. The questions are AI-generated, not official papers, so use the official GATE papers for your final mocks and for NAT and MSQ practice.

Frequently asked questions

How many sections are there in the GATE EE 2027 syllabus?

Ten: Engineering Mathematics, Electric Circuits, Electromagnetic Fields, Signals and Systems, Electrical Machines, Power Systems, Control Systems, Electrical and Electronic Measurements, Analog and Digital Electronics and Power Electronics.

Which subjects matter most in GATE EE?

There is no official weightage. In recent papers, Electrical Machines, Power Systems, Control Systems and Electric Circuits have been the larger blocks, but every section has to be covered, and the 2027 revision makes past patterns less reliable.

Is the GATE EE syllabus different in 2027?

Yes, as for every GATE paper: the 2027 syllabi are the first revision since 2021. The ten sections above are the 2027 EE version. This page does not claim which topics changed from 2026, so compare the EE PDF with your notes and fill any gap.

Can I take GATE EE and EC together?

Yes. EC is on EE's allowed list, and both papers are in one application. EE can also be paired with DA, IN, PH or RA, but not with CS.

Is there an age limit for PSU jobs through GATE EE?

GATE has no age limit, but PSUs set their own. POWERGRID's Engineer Trainee 2027 advertisement sets 28 years as on 31 March 2027. Read each PSU's advertisement for its limit and relaxations.
