Thinking of taking Electronics Technology (Sub. Code 820) as your skill subject this year? This page sets out the complete CBSE Electronics Technology Syllabus Class 11 for the 2026-27 session, so you know exactly what's ahead before you open a textbook. Electronics is a hands-on subject where you move between theory and the lab constantly, and a clear view of the units, marks, and practicals makes it far easier to pace your prep instead of scrambling near the exam. Use it as your study map for the year and for building real, employable skills alongside your core subjects.
CBSE Class 11 Electronics Technology (Subject Code 820) is a skill subject offered under the CBSE Department of Skill Education, aligned to the job role of Installation Technician. It is designed to be studied alongside general education subjects and gives students a working foundation in electronic devices, circuits, and test instruments from the very first year.
The syllabus moves steadily from atomic structure and the cathode ray oscilloscope to voltage and current, semiconductors, transistors, and amplifier applications, with theory and laboratory work carrying almost equal weight. Studying Electronics Technology at this level builds analytical thinking, hands-on testing ability, and circuit reasoning that support both higher studies and entry-level vocational roles in the electronics industry.
Syllabus Highlights & Exam Pattern
CBSE Class 11 Electronics Technology is assessed for a total of 100 marks, consisting of 60 marks for theory and 40 marks for practical work, delivered over roughly 260 periods across the year.
The course is organised into four parts:
- Part A – Employability Skills: five common Level III modules worth 10 marks
- Part B – Subject Specific Skills: the core electronics theory and practical content worth 50 marks
- Part C – Practical Work: practical examination, written test, and viva voce worth 30 marks
- Part D – Project Work / Field Visit: practical file or student portfolio worth 10 marks
Following the latest official CBSE skill education syllabus and the prescribed marks scheme is important so students focus on the right topics and the correct mix of theory and lab assessment throughout the year.

Unit-wise Syllabus Breakdown
The Part B subject content is divided into five units that build in sequence, moving from basic atomic and measurement concepts to semiconductor devices, transistors, and amplifier circuits.

Students are advised to work through the units in order, as each one builds on the previous, and to give Unit 3 extra attention since it carries the highest weightage and feeds directly into the transistor units.
Unit-wise Weightage (High-level)
Some units in Class 11 Electronics Technology carry more marks than others and should be prioritised during preparation.

High-weightage areas:
Unit 3 (Basics of Semiconductor) is the single most important unit at 15 marks and covers diodes, rectifiers, and special circuits that recur throughout the course. The transistor and amplifier units (4 and 5) build directly on it, so strong semiconductor fundamentals pay off across the paper. Exact marks distribution should always be verified using the latest CBSE scheme.
For CBSE students also preparing for Physics at Class 11, the semiconductor and electricity concepts in this subject overlap usefully with CBSE Class XI Physics and CBSE Class XI Mathematics.
Practical & Lab Components
The practical and project component carries 40 marks and focuses on developing real testing, measurement, and circuit-building skills.
- Practical examination on diode, rectifier, transistor configuration, and amplifier experiments
- Written test and viva voce that check understanding of circuit diagrams and observations
- Activities involving component testing, V-I characteristics, gain measurement, and use of instruments like the multimeter, oscilloscope, and signal generator
- Marks awarded for the practical file/portfolio and overall laboratory performance

How to Study Class 11 Electronics Technology Effectively
- Start each unit with the core theory and circuit diagrams before attempting numericals or lab work
- Keep a lab notebook from day one with clean circuit diagrams, readings, and observations
- Move between theory and the breadboard constantly, since the subject rewards hands-on practice
- Master Unit 3 (semiconductors) early, as diodes and rectifiers underpin the transistor units
- Practise reading and drawing symbols, characteristics, and V-I graphs until they are second nature
- Get comfortable with instruments such as the multimeter, CRO, and signal generator before the practical exam
- Revise Employability Skills (Part A) regularly, as it is scoring and common to all skill subjects
- Use the first 30 minutes of every study session strategically — this subject rewards consistent, focused short sessions over cramming
- Understand why your brain forgets what you study and build a revision cycle into your schedule from the start
Plan Your Year With This Syllabus
Treat this as your roadmap for the year: block out time for each unit, lean harder on the heavier ones, and keep the practicals in view from the start rather than the night before. If you are finding it hard to stay on track, read our guide on how to help students stay motivated in Class 11 and 12 and learn why some students learn faster than others to understand how to study smarter.
