Why Download the Class 12 Physics NCERT Book PDF from Collegedunia?
NCERT hosts the same PDFs on its own portal. But the Collegedunia mirror fixes three problems most students hit. Downloads slow down during result-week traffic. There is no quick way to find one chapter from the contents page. And there is no link to notes or solutions.
- Fast chapter-wise downloads: each chapter is a separate 2 to 6 MB file. It opens on phone or laptop without the 200 MB full-book download.
- Direct chapter index: the table above jumps straight to the chapter. You skip the nested menu on ncert.nic.in.
- Hindi-medium files too: each chapter comes in both English and Hindi (Bhautiki), matching what students see in school.
- Linked to the Notes and Solutions: every chapter PDF pairs with the matching Collegedunia notes and step-by-step solutions. The textbook and the explanation sit one click apart.
- Mobile-friendly viewer: open the PDF right in the browser, with no download. Handy for a quick check while clearing a doubt.
- Updated to 2026-27: the version here matches the current trimmed edition. Older 2023 or earlier prints are not hosted, since they hold content the syllabus dropped.

Class 12 Physics NCERT Book: Part 1 vs Part 2 Split
NCERT prints Class 12 Physics as two volumes. Knowing which part holds which chapter helps if you buy the printed book instead of the PDFs.
| Volume | Chapters | Roughly what it covers | Approx page count |
|---|---|---|---|
| Part 1 (Bhautiki Bhag 1 in Hindi) | Ch 1 to Ch 8 | Electrostatics, Current Electricity, Magnetism, Electromagnetic Induction, Alternating Current, Electromagnetic Waves | ~280 pages |
| Part 2 (Bhautiki Bhag 2 in Hindi) | Ch 9 to Ch 14 | Ray Optics, Wave Optics, Dual Nature, Atoms, Nuclei, Semiconductor Electronics | ~230 pages |
The chapter PDFs above let you skip the part-split and grab any chapter on its own. If you read on a phone, use the chapter-wise files. The full Part 1 or Part 2 PDF is better for printing a whole volume into a revision booklet.

What's Changed in the 2026-27 Class 12 Physics NCERT Book
The 2026-27 NCERT Class 12 Physics book has the same structure as the trimmed 2024-25 edition. Here are the main changes carried forward from the earlier print:
- Communication Systems (the old Chapter 15) is removed: it is not in the 2026-27 print. If you use an older edition, skip Chapter 15 fully.
- Semiconductor Electronics (Ch 14) is trimmed: transistor amplifier circuits, oscillators, and logic-gate truth tables are out of scope. Only p-n junction diode characteristics and rectifier circuits stay.
- Magnetism (Ch 5) is shorter: the magnetic dipole moment of a revolving electron is now just a definition with the gyromagnetic ratio result. The full angular-momentum derivation is gone.
- Van de Graaff generator (Ch 2): kept only as a labelled diagram with a 2-line working principle, not as a worked numerical.
- Cyclotron (Ch 4): retained in full as a board-paper-frequency derivation.
- Polarisation by reflection (Ch 10): Brewster's law and its derivation are back in scope after a short removal in earlier editions.
If you have last year's print at home, the chapter-wise PDFs above let you check which sections moved in or out.
How the NCERT Book PDF Pairs with the Other Class 12 Physics Resources
The NCERT Book PDF is the source. Every other Class 12 Physics resource on Collegedunia is built on the chapter numbering and worked examples in this book.
- Class 12 Physics Notes: concept revision drawn from the NCERT chapter, with derivation walkthroughs that match the book's notation.
- Class 12 Physics NCERT Solutions: every back-exercise question worked out, in the order printed in the NCERT chapter.
- Class 12 Physics Formula Sheet: every equation in the NCERT chapter pulled into a compact one-page sheet per chapter.
- Class 12 Physics Exemplar Book PDF: the separate NCERT Exemplar Problems book, with harder problems than the back exercise. Pair it with the Class 12 Physics Exemplar Solutions for worked answers.
- Class 12 Physics Handwritten Notes: notebook-style, scanned-look concept revision of the same NCERT chapters.

5-STEP METHOD · CBSE TOPPER ROUTINE
How to Use the NCERT Book PDF - Class 12 Physics
- 1Read the chapter first. Open the NCERT Book PDF or chapter Notes. The resource assumes you already know the concepts.
- 2Try each question on your own. Write the working in a notebook before you open the answer. Just reading does not build exam speed.
- 3Compare your working to the resource. Mark every step where your method differed. Those are the spots that lose marks on the board paper.
- 4Flag questions taking over 7 minutes. These go on the re-attempt list for the final-week revision pass.
- 5Read the example boxes first, prose second. The worked examples carry the testable patterns. They are the closest thing to a CBSE marking scheme inside the textbook.
- When the Notes or Solutions point to a figure number: open the chapter PDF and scroll to the figure instead of reading a word description. Optics and Magnetism chapters have figures that are hard to describe in words. The original NCERT caption often adds a clarification that the Notes paraphrase loses.
- When you doubt a worked example: each NCERT chapter has 8 to 14 worked examples in the text. Open the Book PDF to check the Notes match the source. This helps when a Solution skips a step that the original example shows in full.
- Before you try Exemplar problems: read the NCERT chapter once, end to end. Exemplar problems assume you know the textbook. Many wrong MCQ options are built around ideas the NCERT chapter mentions in passing but the Notes may cut.
- For Points to Ponder and chapter summaries: the last page of each NCERT chapter has a Points to Ponder list and a summary that students often miss. Both are good 5-minute revision blocks before unit tests. Several CBSE 2-mark short-answer questions in the last five years came almost word for word from the Points to Ponder list.
- For NCERT-only exercises like the "Additional Exercises" block: Chapters 1, 2, 3, 9, and 14 have extra exercises after the main back exercise. These are not in any coaching workbook. They are exactly the board-pattern numericals CBSE has reused in recent years.
- Quick check during JEE Main and NEET practice: when a competitive-exam question feels new, the NCERT chapter PDF is the fastest way to see if the concept is in scope or if the coaching module went past the syllabus.

Ans. Communication Systems (the old Chapter 15) is no longer part of the 2026-27 syllabus and is not included in this NCERT Book PDF index. Students using older editions should skip Chapter 15 entirely.
Ques. Is the NCERT Book enough on its own to crack the Class 12 Physics board paper?
Ans. For a 70 to 80 mark score, yes. The NCERT chapter text, worked examples, and back exercises together cover everything on the CBSE board paper. For 90 plus, add the Exemplar problems and one previous-year-paper round. Toppers said NCERT-only study gets you to the upper 70s. The last 10 to 15 marks need Exemplar-level practice.
Ques. What does Class 12 Physics cover?
Ans. Class 12 Physics has 14 chapters. They cover electrostatics, current electricity, magnetism, electromagnetic induction and alternating current, electromagnetic waves, ray and wave optics, modern physics (photoelectric effect, atoms, nuclei), and semiconductor electronics. The course is the base for the CBSE Class 12 boards and the Physics sections of JEE Main, JEE Advanced, and NEET.
Ques. Why use the Collegedunia NCERT Book PDF mirror instead of ncert.nic.in?
Ans. The PDFs are the same, since Collegedunia mirrors the official files. The gains are practical. Downloads are faster during busy weeks like result time. You get direct chapter links instead of a nested menu. And each chapter links to the matching Notes and Solutions.
Ques. Is the NCERT Book PDF useful for JEE Main and NEET preparation?
Ans. Yes. NCERT is the base text for both JEE Main and NEET Physics. The chapter coverage and worked examples in the NCERT Book match the JEE Main and NEET syllabus closely. Coaching institutes keep telling students to read the NCERT chapter deeply before starting any coaching module.
