Chapter-wise weightage and study hours
Weightage is the chapter's share of past-paper questions, normalised within its subject; hours are a first pass without revision.
UPSC publishes no unit-level weightage for optionals, and past-paper splits are not reliable enough to use, so units share each paper equally.
Paper 1 250 marks · 200 h
| # | Chapter / topic | Share of paper (equal split) | Study hours |
|---|---|---|---|
| 1 | Circuit Theory | 12% | 25 |
| 2 | Signals and Systems | 12% | 25 |
| 3 | E.M. Theory | 12% | 25 |
| 4 | Analog Electronics | 12% | 25 |
| 5 | Digital Electronics | 12% | 25 |
| 6 | Energy Conversion | 12% | 25 |
| 7 | Power Electronics and Electric Drives | 12% | 25 |

Log scores from any test series. Chapters that went badly are marked weak and revised sooner.
Frequently asked questions
Which chapters carry the most weight in UPSC Electrical Engineering optional?
Going by our compiled weightage, the heaviest chapters are Control Systems, Microprocessors and Microcomputers, Measurement and Instrumentation, Power Systems: Analysis and Control, Power System Protection. They are worth starting early, but past papers vary from year to year, so plan to cover the whole syllabus.
Is this UPSC Electrical Engineering optional weightage official?
No. UPSC publishes the syllabus, not chapter weightage. These numbers come from analyses of previous years' papers, so treat them as a guide to priority, not a promise of what will be asked.
How many hours does the UPSC Electrical Engineering optional syllabus take?
Our first-pass estimate adds up to about 400 hours of study, before revision and mock tests. At 6 hours a day, 6 days a week, that is roughly 2.6 months. Daily Tayyari replaces these defaults with your actual pace after the first week or two.
Does the Electrical Engineering optional overlap with General Studies?
Not much directly, so plan it as a separate block with its own answer-writing practice.
Can any graduate choose this optional?
Yes. UPSC lets candidates pick any optional from the list regardless of their graduation subject. Interest, available material and overlap with GS are the usual deciding factors.
Is Daily Tayyari free, and does it work in Hindi?
Yes. It is free with no ads and no payment; you sign in with Google only so your plan is saved. You can switch between Hindi and English at any time, and chapter names are shown in both.
