NCERT solutions for class 12 physics- chapter wise
Chapter 1 Electric Charges And Fields: You must have seen a spark or have heard a crackle when you take off your synthetic or woollen clothes mainly in dry weather. Do you know why this happens? Well, this happens due to the discharge of electric charges from our body or in scientific words, this happens due to the generation of static electricity. The first chapter of NCERT class 12 talks about the charges at rest, their properties, the force experienced by a charge and the electric field due to different system of charges. This chapter has 24 questions and 10 additional questions hence a total of 34 questions. You will find the ncert solutions class 11 physics here.
Chapter 2 Electrostatic Potential And Capacitance: This chapter is the continuation of physics NCERT class 12 chapter 1. This chapter has mainly two concepts that are the potential due to charges and capacitance. If you remember concepts of mechanics then you can relate the concepts of this chapter to mechanics, like potential energy is equivalent to electric potential energy, the mechanical dipole is equivalent to the electric dipole, etc. This chapter has 11 questions and 26 additional questions, hence a total of 37 questions.

The chapter basically deals with the steady motion of charges and moves on to the study of the rate of motion of charge, Ohm’s law and Kirchoff’s law. The chapter also introduces the concept of certain measuring instruments like Wheatstone bridge, potentiometer, ammeter, and voltmeter.
Chapter 4 Moving Charges And Magnetism: The moving charge under a magnetic field can produce a force. This NCERT class 12 chapter 4 talks about moving current-carrying conductors in a magnetic field and about the magnetic effects produced by these conductors. You will basically find how a charged particle or current-carrying wire behaves in the presence of a magnetic field. You will also get to know how can current produce a magnetic field. The chapter has 13 questions and 15 additional questions. Click on the link above to get the solutions.
Chapter 5 Magnetism And Matter: This chapter talks about earth's magnetism and magnetic materials and their properties. The earth behaves as a magnet with a magnetic field pointing from south to north. This chapter also tells about the properties of bar magnets. The chapter has 15 questions and 10 additional questions. You will find all the class 12 physics NCERT solutions chapter 5 here. You can also download solutions for offline use.
Chapter 6 Electromagnetic Induction: In NCERT class 12 physics chapter 4 it is mentioned that a current-carrying conductor in a magnetic field can produce a force. Whereas in the chapter Electromagnetic Induction we study about a moving conductor in a magnetic field that can produce a current. This principle is used in AC (Alternating Current) generators and the term AC is studied in detail in the next chapter. The chapter has a total of 17 questions out of which 10 questions are from the exercise and 7 are additional questions.
Chapter 7 Alternating Current: Do you know why most of the devices require AC voltages rather than DC voltages. The reasons for preferring AC over DC are mainly the easiness of converting one type of voltage into another (higher voltage to lower or vice-versa) via use of transformers. Also, the energy losses are less in AC as compared to DC. The CBSE NCERT solutions for class 12 physics chapter 7 introduces the concept of alternating current and various circuit elements. It also introduces the concept of single-phase transformers. The chapter has 11 questions and 15 additional questions.
Chapter 8 Electromagnetic Waves: The last chapter of class 12 physics NCERT book part 1 has 10 questions and 5 additional questions and you will find all the solutions by clicking the chapter link. The chapter introduces some modifications in some laws studied in previous chapters and introduces the electro-magnetic properties of light. All these 8 chapters of NCERT class 12 physics Part 1 are related to each other.
Chapter 9 Ray Optics And Optical Instruments: Chapter 9 of physics NCERT book for class 12 introduces the concept of reflection, refraction, and dispersion of light considering light as a ray. You will get to know how different reflecting surfaces (plane, convex or concave mirrors, etc) and refracting surfaces ( convex or concave lens) form images of the different objects. This chapter is really very important for boards as well as exam perspective, hence you should solve each and every question carefully. The chapter has 38 questions in total.
