Ncert Solutions Physics Class 12th

The NCERT solutions offer all the theoretical and numerical textbook problems through a structured and simplified explanation, hence it is highly beneficial to prepare from here. Chapter 4 contains complex vector-based concepts like the motion of charged particles, magnetic force, and Biot–Savart la

The principle that a current-carrying coil placed in a magnetic field feels a torque is behind a moving coil galvanometer. The coil rotates due to this torque, and the angle of deflection is proportional to the current. For the conversion of a galvanometer into an ammeter, a high current is allowed

This force is exerted by the magnetic fields produced by the parallel current-carrying conductors. If the currents run in the opposite directions, they repel and if they run in the same direction, then they attract. The force is exerted because each conductor lies in the magnetic field produced by t

When electric current passes through a long coil of wire, it generates a nearly uniform magnetic field inside it, it is the solenoid. Outside this solenoid, the magnetic field is weak and negligible. On the other hand, in a toroid, the magnetic field is completely confined within its core, which for

The concepts help students to introduce the magnetic effects produced by electric currents. These concepts are important for the theoretical and applied physics. It includes the key concepts which are fundamental to understanding magnetic fields and serves as the foundation for many devices. Such ke

Kirchhoff's laws include the Loop Rule (KVL) and the Junction Rule. These are helpful in analyzing complex electrical circuits. The solutions explain the concepts behind these laws and help them in applying in various example problems involving the EMF sources and multiple resistors. By thoroughly p

According to the class 12 Physics chapter 3 NCERT solutions, Ohm's Law is a foundational principle in electrical circuits. It states that when the temperature is constant, the current passing through a conductor is directly proportional to the voltage across it. The NCERT solutions explain the law u

The Class 12 Physics Chapter 3 NCERT solutions focus on understanding the electric charge movement and the factors affecting it. The main topics include drift velocity, current density, electric current, resistivity, resistance, Ohm's law, internal resistance, the combination of resistors in series

Chapter 3 Current Electricity offers various numerical problems related to resistance, current, energy, power, circuit laws and EMF. The solutions given here give a systematic approach to solving NCERT problems, selecting the appropriate formula, starting from identifying the known and unknown varia

Yes, mastering the NCERT concepts is more than sufficient to score high in the board exams. Most of the questions in the Class 12 board exam are based on NCERT textbook content. Hence, the students can build a strong understanding of the important topics and numerical problem solving by regularly us
