Class 12 Physics Revision Notes 2026-27: Chapter-Wise PDF for CBSE Boards (All 14 Chapters)
eSaral Academic and Editorial Team
Summary
Class 12 Physics revision notes for CBSE 2026-27 cover all 14 chapters in chapter-wise PDFs, from Electric Charges and Fields to Semiconductor Electronics. This page lists the PDFs, the unit-wise marks of the 70-mark theory paper and a simple revision plan, so you can revise the full syllabus before the board exam.
Class 12 Physics revision notes are short, chapter-wise notes that you use after you have studied the full chapter. They put the main concepts, definitions, diagrams and formulae in one place, so that you can revise quickly instead of re-reading the textbook. These Class 12 Physics revision notes by eSaral follow the 14-chapter rationalised syllabus. Use them together with the NCERT textbook, and download the textbook from eSaral’s NCERT Class 12 books page.

Chapter | Chapter name | CBSE unit | Revision notes PDF |
|---|---|---|---|
1 | Electric Charges and Fields | Electrostatics | |
2 | Electrostatic Potential and Capacitance | Electrostatics | |
3 | Current Electricity | Current Electricity | |
4 | Moving Charges and Magnetism | Magnetic Effects of Current and Magnetism | |
5 | Magnetism and Matter | Magnetic Effects of Current and Magnetism | |
6 | Electromagnetic Induction | Electromagnetic Induction and Alternating Currents | |
7 | Alternating Current | Electromagnetic Induction and Alternating Currents | |
8 | Electromagnetic Waves | Electromagnetic Waves | |
9 | Ray Optics and Optical Instruments | Optics | |
10 | Wave Optics | Optics | |
11 | Dual Nature of Radiation and Matter | Dual Nature of Radiation and Matter | |
12 | Atoms | Atoms and Nuclei | |
13 | Nuclei | Atoms and Nuclei | |
14 | Semiconductor Electronics: Materials, Devices and Simple Circuits | Electronic Devices |
Note on Chapter 14: The Chapter 14 PDF covers more than the CBSE board syllabus now includes (for example, transistor action, amplifiers, logic gates and integrated circuits). Published deleted-syllabus lists show that CBSE has removed the Zener diode, LED, photodiode and solar cell, and earlier removed transistors and logic gates, from the board syllabus. For board exams, follow the latest CBSE syllabus. Logic gates are still useful for competitive exams such as JEE Main and NEET.
Class 12 Physics Revision Notes: Unit-Wise Marks 2026-27
The CBSE Class 12 Physics theory paper (subject code 042) is for 70 marks, and 30 marks are for practicals. The syllabus has 9 units, and CBSE gives the marks for groups of units, as shown below.
CBSE units | Chapters | Marks |
|---|---|---|
Unit I Electrostatics and Unit II Current Electricity | 1, 2, 3 | 16 |
Unit III Magnetic Effects of Current and Magnetism and Unit IV Electromagnetic Induction and Alternating Currents | 4, 5, 6, 7 | 17 |
Unit V Electromagnetic Waves and Unit VI Optics | 8, 9, 10 | 18 |
Unit VII Dual Nature of Radiation and Matter and Unit VIII Atoms and Nuclei | 11, 12, 13 | 12 |
Unit IX Electronic Devices | 14 | 7 |
Total theory | 70 |

What Do the Class 12 Physics Revision Notes Contain?
The chapter PDFs are written as concise notes. They give the theory in numbered sections with headings, the definitions and principles, diagrams, and the main formulae of each chapter. Use them like this:
- Before the exam: read a chapter’s notes, and then close them and write the formulae from memory.
- After studying a chapter: compare your own notes with these notes, and fill in any missing points.
- With NCERT: use the notes for revision, and use the NCERT textbook and exercises for practice.
How to Use the Class 12 Physics Revision Notes for the Board Exam
- Finish the chapter first. Study the chapter from your textbook or class notes, because revision notes are for revision.
- Read the notes once, and mark weak topics. Then go back to the textbook for those topics.
- Practise NCERT questions. Use eSaral’s NCERT Solutions for Class 12 Physics to check your answers step by step.
- Use the marks table to plan. Spend more time on the groups that carry more marks: Electromagnetic Waves and Optics (18), Magnetism with EMI and AC (17), and Electrostatics with Current Electricity (16).
- Revise by recall. Write down formulae and derivations from memory after each chapter, and then check them with the notes.
Writing your own notes also helps. Our guide on how to make notes for JEE shows a good method.
Frequently Asked Questions
Are Class 12 Physics revision notes available for free?
Yes. All 14 chapter-wise Class 12 Physics revision notes PDFs on this eSaral page are free to download, with no sign-up needed.
How many chapters are there in the Class 12 Physics revision notes?
The Class 12 Physics revision notes have 14 chapters, from Chapter 1 (Electric Charges and Fields) to Chapter 14 (Semiconductor Electronics: Materials, Devices and Simple Circuits). Each chapter has its own PDF.
Are these Class 12 Physics revision notes enough for the CBSE board exam?
They are good for revision, but they should not replace the NCERT textbook and exercises. Study each chapter from the textbook, solve the NCERT questions, practise previous year papers and use the notes for quick revision. Check Chapter 14 against the latest CBSE syllabus, because some topics in the PDF are no longer in the board syllabus.
What are the unit-wise marks in the CBSE Class 12 Physics paper?
The 70-mark theory paper has these marks for groups of units: Electrostatics and Current Electricity 16, Magnetic Effects of Current and Magnetism with Electromagnetic Induction and Alternating Currents 17, Electromagnetic Waves and Optics 18, Dual Nature of Radiation and Matter with Atoms and Nuclei 12, and Electronic Devices 7.
Can I use these revision notes for JEE Main and NEET?
They cover the NCERT concepts that JEE Main and NEET are built on, so they are useful for revision. For JEE Main you also need more difficult numericals, and you should check the JEE Main and NEET syllabi for topics such as logic gates.
What is the difference between revision notes and NCERT solutions?
Revision notes summarise the concepts and formulae of a chapter. NCERT solutions give step-by-step answers to the textbook exercise questions. Use the notes to revise the theory, and use the solutions to check your problem-solving. eSaral has both for Class 12 Physics.
How much time should I spend on each chapter’s revision notes?
A common plan is 30 to 45 minutes for a first revision of a chapter, and more for chapters with many derivations and numericals, such as Ray Optics or Current Electricity. Regular short sessions work better than last-minute cramming.
Which Class 12 Physics chapters carry the most marks?
CBSE gives the most marks to the group of Electromagnetic Waves and Optics (18 marks), followed by Magnetism with EMI and AC (17 marks) and Electrostatics with Current Electricity (16 marks). Plan your revision around these groups.
Do the Class 12 Physics revision notes include practical work?
The PDFs cover the theory chapters. The practicals carry 30 marks in the CBSE Class 12 Physics scheme, so prepare for them separately with your school’s lab manual.
