NCERT Book for Class 12 Physics
If you are a Class 12 student preparing for your board exams, the NCERT Physics textbook is the most important resource you need. Whether you study under CBSE or any other board that follows the NCERT curriculum, this book covers every concept, law, and theory that your exam will test. On this page, you can access the latest edition of the NCERT Class 12 Physics book for educational reference and study purposes.
The book is divided into two parts. Part 1 covers topics from electricity and magnetism, while Part 2 goes into optics, modern physics, and semiconductors. Together, these two books form the complete Class 12 Physics course as prescribed by NCERT and followed by CBSE-affiliated schools across India.
About the NCERT Class 12 Physics Book
The NCERT Class 12 Physics textbook is prepared by subject experts and goes through a careful review process before publication. It is written in clear, simple language that makes even complex topics easy to understand. The book includes solved examples, in-text exercises, and end-of-chapter questions that help students test their understanding as they study.
This textbook is the base for:
CBSE Class 12 board exam preparation
JEE Main and JEE Advanced (physics concepts directly from NCERT)
NEET (for the physics section)
CUET and various state board entrance tests
Because so many competitive exams draw questions from NCERT content, reading and understanding this book thoroughly is not just enough for boards — it is a strong foundation for entrance exam success too.
NCERT Class 12 Physics Part 1 – Chapter Overview
Part 1 of the Class 12 Physics book contains 8 chapters focused on electricity, magnetism, and electromagnetic waves.
Chapter 1: Electric Charges and Fields
This chapter introduces the concept of electric charge, Coulomb's Law, and the principle of superposition. Students learn about electric field lines and Gauss's Law, which are used to calculate electric fields due to various charge distributions. It is an important chapter for both theory and numericals.
Chapter 2: Electrostatic Potential and Capacitance
Here you will study electrostatic potential, equipotential surfaces, and capacitance. The chapter explains dielectrics, polarisation, and how energy is stored in capacitors. Practical applications make this chapter very useful for real-world understanding.
Chapter 3: Current Electricity
This chapter focuses on the flow of electric current in conductors. Topics include Ohm's Law, resistivity, Kirchhoff's Laws, the Wheatstone Bridge, and the meter bridge. Circuit-based numerical problems from this chapter appear frequently in board exams.
Chapter 4: Moving Charges and Magnetism
Students learn about the magnetic effects of electric current, the Biot-Savart Law, Ampere's Circuital Law, and the Lorentz Force. Motion of charged particles in magnetic fields is covered in detail and is highly relevant for entrance exams.
Chapter 5: Magnetism and Matter
This chapter covers magnetic materials, magnetisation, and magnetic susceptibility. The Earth's magnetism and the properties of diamagnetic, paramagnetic, and ferromagnetic materials are explained with clear examples.
Chapter 6: Electromagnetic Induction
Faraday's Laws, Lenz's Law, induced EMF, self-induction, mutual induction, and eddy currents are the key topics here. Real-life applications like electric generators and transformers make this chapter both important and interesting.
Chapter 7: Alternating Current
Students study AC circuits, phasor diagrams, reactance, impedance, resonance, LC oscillations, and power in AC circuits. This chapter forms a strong base for electronics and engineering entrance preparation.
Chapter 8: Electromagnetic Waves
This chapter explains how electric and magnetic fields combine to create electromagnetic waves. The full electromagnetic spectrum is covered, from radio waves to gamma rays, with their properties and practical uses.
NCERT Class 12 Physics Part 2 – Chapter Overview
Part 2 contains 6 chapters covering optics, modern physics, and semiconductor electronics.
Chapter 9: Ray Optics and Optical Instruments
Students learn about reflection and refraction, mirrors and lenses, and optical instruments like microscopes and telescopes. Ray diagrams and formula-based questions are common in board exams from this chapter.
Chapter 10: Wave Optics
This chapter introduces the wave nature of light. Topics include Huygens' principle, interference, diffraction, and polarisation. The famous Young's Double Slit Experiment is explained in detail and forms the core of wave optics numericals.
Chapter 11: Dual Nature of Radiation and Matter
Here, concepts from both classical and quantum physics come together. The photoelectric effect, Einstein's photoelectric equation, and de Broglie's hypothesis on matter waves are the main topics. This chapter is essential for NEET and JEE preparation.
Chapter 12: Atoms
Students study Rutherford's model, Bohr's atomic model, energy levels, and spectral series. The chapter helps explain how electrons behave inside atoms and how atomic spectra are produced.
Chapter 13: Nuclei
The structure of the nucleus, radioactivity, half-life, mass-energy equivalence, nuclear fission, and nuclear fusion are all covered here. This chapter is fundamental for understanding modern nuclear science and energy production.
Chapter 14: Semiconductor Electronics: Materials, Devices and Simple Circuits
The final chapter covers semiconductors, p-n junction diodes, transistors, logic gates, and basic digital circuits. It forms the foundation of electronics and is directly useful for engineering studies.

How to Study NCERT Class 12 Physics for Best Results
Simply having the book is not enough. How you use it makes all the difference. Here are some practical tips:
Read every line carefully. NCERT books are concise, which means every sentence matters. Do not skip paragraphs.
Solve all in-text and end-of-chapter questions. These are often directly asked in CBSE board exams.
Make short notes chapter by chapter. Writing down formulas, laws, and key concepts in your own words helps retain them.
Draw diagrams while reading. Physics has many circuit diagrams, ray diagrams, and wave diagrams. Practise them regularly.
Revise with previous year papers. Check which chapters and topics are asked most frequently and give them extra attention.
Use NCERT Exemplar for extra practice. After finishing each chapter in the main book, solve Exemplar problems to strengthen your understanding.
Why NCERT Books Are the Best Starting Point
Students sometimes wonder whether they should jump straight to reference books like H.C. Verma or D.C. Pandey. The answer is always the same: start with NCERT and build a solid base first.
Here is why NCERT Physics is so important:
All CBSE board exam questions are based on the NCERT syllabus and textbook content
The language is simple and the explanations are clear, even for difficult topics
Diagrams and solved examples in the book are clear enough to understand without a teacher
The book covers the exact topics prescribed in the CBSE syllabus, nothing more and nothing less
It is freely available and accessible to every student across India
Reference books are useful for entrance exam preparation, but only after you have a strong grasp of the NCERT content.
