NCERT Solutions for Class 12 Physics (Chapter-wise Description)
Chapter 1: Electric Charges and Fields
NCERT Class 12 Physics Chapter 1- Electric Charges and Fields is centred on the concepts revolving around an electric charge and electric field. In this chapter, you will revisit the topics from earlier classes such as the difference between insulators and conductors, Coulomb’s law etc.
In addition to previous learning, we will delve deeper into the concept of electrostatic forces. Other important topics of the chapter include electric field intensity, electric field lines, electric dipole moment, torque etc.
Chapter 2: Electrostatic Potential And Capacitance
In NCERT Class 12 Physics Chapter 2- Electrostatic Potential and Capacitance, you will learn about a new topic electrostatic potential. Further, you will study about equipotential surface, potential energy in an external field, and electrostatic shielding.
Chapter 3: Current Electricity
NCERT Class 12 Physics Chapter 3- Current Electricity will provide you with in-depth information about the working of electric current. You will also learn about how the electric charge flow in metallic conductors. Further, you will revisit topics from earlier classes such as Ohm’s law, resistance, resistivity etc.
The relationship between resistivity and relaxation time, colour code of resistance, a combination of resistance etc are the most important topics of this chapter.
Chapter 4: Moving Charges And Magnetism
NCERT Class 12 Physics Chapter 4 - Moving Charges And Magnetism will help you gain in-depth knowledge about magnetic field. Key topics of this chapter are Biot-Savart’s law, Ampere’s circuital law, magnetic field due to a straight solenoid, and magnetic field due to the toroidal solenoid.
Chapter 5: Magnetism And Matter
NCERT Class 12 Physics Chapter 5 - Magnetism And Matter contain topics that are based on the concepts of the previous chapter. In this chapter, you will learn about Coulomb’s law in magnetism, magnetic field lines, torque, potential energy, oscillation of a freely suspended magnet etc.
Next, you will come across formulas of magnetism that you can easily remember from your previous knowledge of the chapter electrostatics.
Chapter 6: Electromagnetic Induction
NCERT Class 12 Physics Chapter 6 - Electromagnetic Induction consist of important laws of physics in the branch of electronics. Faraday’s law of electromagnetic induction, Lenz’s law, motional emf, Fleming’s right hand rule are the most important topics of this chapter.
Chapter 7: Alternating Current
NCERT Class 12 Physics Chapter 7 - Alternating Current is one of the most important chapters as it will help you gain knowledge about rms value of AC, mean value of AC, alternating emf, inductive reactance, power, and wattless current.
Chapter 8: Electromagnetic Waves
NCERT Class 12 Physics Chapter 8 - Electromagnetic Waves consist of topics that are in continuation to what you already studied in previous chapters. To start, you will first study the displacement current and its uses.
Later in the chapter, you will study Maxwell’s equations of electromagnetic waves, electromagnetic waves and its types, electromagnetic spectrum etc.
Chapter 9: Ray Optics And Optical Instruments
NCERT Class 12 Physics Chapter 9 - Ray Optics and Optical Instruments include various familiar topics such as reflection and its laws, mirror formula, magnification, refraction and its laws, total internal reflection, to name a few. Later in this chapter, you will study the principle of reversibility, refractive index, lens maker’s formula, Rayleigh law of scattering etc.
Chapter 10: Wave Optics
NCERT Class 12 Physics Chapter 10 - Wave Optics describes the relation between waves and rays of light. Huygens’ principle is an important law of optics, which will help you determine the shape of the wave front. In the latter half of the chapter, you will study the behaviour of a prism, lens and spherical mirror towards plane wave front.
At the brink of conclusion, this chapter will entail the law of refraction on the basis of Huygens’ wave theory.
