Chapter 1: Electric Charges and Field
You start your journey with a detailed look into the types of electric charge and its fields, transference of electrons, conservation of charge, additivity of charges, quantization of charge, Gauss’s law, etc.
Chapter 2: Electrostatic Potential and Capacitance
Chapter 2 will help students understand the electrostatic potential, the electrostatic potential difference between two points in an electric field, the relationship between electric field and potential gradient, and the different formulas to help students gain more practical insight into the chapter.
Chapter 3: Current Electricity
This is one of the most important chapters in the NCERT Class 12 Physics book. This chapter elaborates on the previous concepts of electricity and helps students understand current density, Ohm’s law, drift velocity, how electric charge flows in solid metallic conductors and liquid conductors, etc. It also has numerical problems for students to solve.
Chapter 4: Moving Charges and Magnetism
This chapter develops the foundation required to tackle the later chapters of the NCERT Class 12 Physics book. It talks about magnetic force and motion in a magnetic field. It gives students an insight into Biot-Savart’s Law, Ampere’s Circuital Law, the Solenoid and the Toroid, etc.
Chapter 5: Magnetism and Matter
Chapter 5 dives deeper into the concept of magnetism. It will provide details about Magnetism and Gauss’s law, a bar magnet, the magnetic properties of different materials, the properties of magnetic field lines and the Electrostatic Analog.
Chapter 6: Electromagnetic Induction
In the previous classes, you have learned about electromagnetic induction in brief. In this chapter, you will get a detailed look into the different topics related to electromagnetic induction like magnetic flux, eddy currents, motional electromotive force, a quantitative study on energy consideration, Lenz’s Law, Fleming’s Right Hand Rule, the laws of Faraday’s Law of Electromagnetic Induction, etc.
Chapter 7: Alternating Current
What is alternating current, and what are the different aspects of alternating current? Chapter 7 will teach students about alternating current, AC voltage applied to a resistor, AC voltage applied to a series LCR circuit, power in an AC circuit, transformers, and many more topics.
Chapter 8: Electromagnetic Waves
Chapter 8 discusses three crucial topics related to Electromagnetic waves: Displacement current, electromagnetic waves, and the electromagnetic spectrum. Students will engage with Maxwell’s Equation of Electromagnetic waves, understand the uses of electromagnetic waves in radio waves, microwaves, etc., their frequency range and wavelength range, detection channels, and many other topics related to electromagnetic waves.
Chapter 9: Ray Optics and Optical Instruments
This is another vital chapter in the NCERT Class 12 Physics book. Chapter 9 introduces students to ray optics and optical instruments, reflection of light by spherical mirrors, total internal reflection, refraction, dispersion and refraction by a prism, and some natural phenomena occurring due to sunlight.
Chapter 10: Wave Optics
Chapter 10 will shift from Ray optics to Wave optics. It will go into details of wave optics, Huygens Principle, Refraction and Reflection of Plane Waves using Huygens Principle, polarisation, interference of light waves and Young’s Experiment, and the application of wave optics like in 3D glasses, etc.
Chapter 11: Dual Nature of Radiation and Matter
What are the properties of radiation? Does it resemble a particle or a wave or both? This chapter talks about the dual nature of radiation and tackles topics like electron emission, photoelectric effect, Einstein’s Photoelectric Equation, Wave Theory of Light, Wave Nature of Matter, etc.
Chapter 12: Atoms
Atoms are the basic unit that makes up matter. Chapter 12 talks about the organic and inorganic objects that make up atoms. This chapter will discuss Alpha-particle Scattering, Rutherford’s Nuclear Model of Atom, Bohr Model of the Hydrogen Atom, Atomic Spectra, etc.
Chapter 13: Nuclei
At the core of the atom, there is a nucleus. This chapter will introduce students to the nuclei, the composition and size of the nucleus, nuclear energy, nuclear force and radioactivity. It will also talk about how nuclear energy can help to tackle the energy crisis we face today.
Chapter 14: Semiconductor Electronics Materials Devices And Simple Circuits
This is an essential chapter in the Physics Class 12 NCERT book. Chapter 14 will elaborate on important topics like the types of semiconductors and insulators; classification of metals, conductors and semiconductors; extrinsic and intrinsic semiconductors, etc.
Chapter 15: Communication Systems
The last chapter of the NCERT 12 Physics book will enter the world of communication systems. It will talk about the basic elements of communication: Transmitter, channel and the receiver. It will talk about each of their roles, bandwidth of signals and transmission medium, amplitude modulation, propagation of electromagnetic waves, etc.
The chapters in the NCERT Class 12 Physics book may be diverse, but they are equally interesting for any Physics lover. However, it might be difficult for you to always carry the thick Physics book around and make constant notes in a separate copy. Then, why don’t you opt for the NCERT book for Class 12 physics PDF?
