Electricity plays a vital role in our daily lives, and its two main forms are Direct Current (DC) and Alternating Current (AC). While DC flows in a single direction, AC changes its direction periodically. Alternating Current is the backbone of modern power systems because it is easier to transmit over long distances, can be transformed …

Physics plays a vital role in understanding the basic principles governing the natural world. One such significant topic in Class 12 Physics is Moving Charges and Magnetism. This chapter connects two essential concepts: electricity and magnetism. We have learned that a stationary charge produces an electric field. However, when the charge moves, it produces both …
Electromagnetic Induction (EMI) is one of the most important topics in Class 12 Physics. It deals with the phenomenon of producing electric current using a changing magnetic field. This concept was first discovered by Michael Faraday in 1831, and it laid the foundation for modern-day electrical engineering, including generators, transformers, and induction motors. In simple …
Magnetism is a fundamental property of materials that causes them to experience a force in the presence of a magnetic field. The chapter Magnetism and Matter in Class 12 Physics deals with concepts such as the Earth’s magnetism, magnetic properties of materials, magnetic dipole, magnetic field intensity, magnetic susceptibility, and so on. Understanding these topics …
Electrostatics is one of the most important chapters in Class 12 Physics. After learning about Electric Charges and Fields, the next crucial topic is Electrostatic Potential and Capacitance. This chapter deals with concepts like electric potential, potential difference, energy in electric fields, capacitors, and their applications. A strong understanding of these topics helps in solving …
Electricity is one of the most fascinating branches of physics. The study of electric charges, their properties, and the fields they create is fundamental to understanding modern technology and natural phenomena.
