Introduction Ampere’s law placed a milestone for the development of Electrodynamics. Hans Oersted in 1920 performed a classic experiment with a compass needle and current carrying conductor. He observed that if there is no current in the wire then the compass needle always points towards the north pole. However, in ... Read More

Introduction Our universe is 13.8 billion years old, on average. The age of the earliest stars and the rate of the universe's expansion was calculated by scientists to arrive at that number. Edwin Hubble discovered in 1924 that the speed at which astronomical objects travel apart is a function ... Read More

Introduction AC voltage is caused by an alternating current. The change in magnetic flux, when a current-carrying conductor is allowed to rotate in a magnetic field, induces an alternating voltage in the coil. This is known as induced electromotive force. The inductor is a coil of wire in which back ... Read More

Introduction Bragg’s law is an important concept of atomic and molecular physics. You are already aware that atoms are the building blocks of this universe. They are the foundation of every bit of matter in this universe. But that is not all that we know about the microscopic world. Indeed, ... Read More

Introduction Bridge is a structure that carries pathways, railroads, or other such things across an obstacle. But bridges themselves are much more intricate. Their beauty lies in the abilities granted to them by their design. Indeed, architects and engineers have now been able to design bridges without support in between, ... Read More

Introduction Thermal energy or heat energy is transferred from one object to another. This may happen due to three different possibilities. They are conduction, convection, and radiation. In the conduction process, the energy is transferred from one object to another without the movement of the particles. In the convection process, ... Read More

Introduction In an electrical circuit, the main components are current, voltage, and resistance. The electric current is the flow of charge. The voltage supply works as the energy source for these charges for movement. We can understand the concept of potential by taking the example of water flow. Water always ... Read More

Introduction Kirchhoff’s law is used to study the electrical energy used in a circuit. The movement of the charged particles is responsible for electric energy. Energy obtained from the kinetic energy or potential energy of the charged particles is the electric energy. Charged particles are atoms, molecules, or ions that ... Read More

Introduction Dielectrics materials plays a major role while studying Solid State Physics. As we know matter can be found in three states. They are gaseous state, solid state and liquid state. Atoms or ions or molecules combine to form a substance. Solid State Physics is a branch of physics that ... Read More

Introduction The atom was known to be electrically neutral through the pioneering studies of scientists such as J.J. Thomson and A. Rutherford who carried out their research in the late 19th and early 20th centuries. An atom consists of elementary electric charges. The force between electric charges is called electric ...
