Introduction Dielectric strength is a property of insulating materials. Electricity is the utility power that drives the entire world's equipment in the way that we see it today. The transmission and distribution of electric power for industrial and household purposes are through insulated cables. Dielectric strength materials available intrinsically in cable insulations. The dielectric strength prevents electricity leakage from the transmission strands (usually copper) inside the insulation. This tutorial covers the definition, methods of ascertaining the dielectric strength of a material, and other related concepts core to dielectric strength. Dielectric Materials Some insulating materials have the functionality of storing ... Read More

Introduction Diatomic gases are plenty in nature. A two-atom molecule is referred to as a diatomic molecule. At normal temperatures, almost all diatomic molecules are gases. Diatomic molecules are found in substances like carbon monoxide and nitric oxide. What is a Diatomic Molecule? Diatomic molecules or elements are those that have two atoms linked together chemically. When two atoms are identical, as in the case of the oxygen molecule, they combine to form a homonuclear diatomic molecule; but, when they are dissimilar, as in the case of carbon monoxide, they combine to produce a heteronuclear diatomic molecule. Heat capacity ... Read More

Introduction Destructive interference is a concept based on superposition of waves. Wave is the disturbance in a medium to transfer energy without the transfer of mass. Waves are usually in a periodic motion, like a simple harmonic oscillator. They have crests and troughs. The amplitude of the wave is the height of the wave. The distance covered between two consecutive crests is called the wavelength of the wave. The number of waves passed per second is called the frequency of the wave. Phase is not the property of waves. But it gives the relation between two signals with the same ... Read More

Introduction Aerofoil terminologies and lift coefficient are important concepts to determine the design of a flying object. Have you ever wondered how aeroplanes stay up in the air? What is it about their design that allows them to soar across the sky? The answer, as it turns out, is as interesting as the question. Let us start by discussing the forces that aid in keeping aeroplanes up in the air. These are four in number, and we call them drag, thrust, weight, and lift. Together, they make it possible for aeroplanes to fly. Of these, the concept of lift is ... Read More

Introduction Gamow theory of Alpha decay explains the radioactive process of decay effectively. Elements in nature are flexible. That is, to say, it is possible to convert one element into another by various processes that are classified as nuclear reactions. For example, there is a type of nuclear reaction called nuclear decay, which occurs when the nucleus of an element is unstable and releases energy, nucleons, and/or atoms to achieve stability. One special type of nuclear decay is alpha decay which occurs when an atomic nucleus decays into another one by releasing an alpha particle. Note that an alpha ... Read More

Introduction Artificial Transmutation is the process in which one element changes into another element in decay artificially. This conversion may be natural or artificial. In Artificial Transmutation one element is changed into another element by bombarding fundamental particles like an alpha particle, proton neutron, deuteron, etc. An unstable nucleus undergoes the natural transmutation process but in artificial transmutation, the atoms of the element are encountered with the fundamental particle and form a new element in the decay process. Now let's understand all the terminology related to the artificial transmutation in detail in this article. What is Artificial Transmutation? Transmutation ... Read More

Introduction Direct current generator produces electric current by the process of electromagnetic induction. The electromagnetic force gives rise to the electromagnetic field. In an electromagnetic field, the electric field and the magnetic field are intertwined. Electromagnetic force determines electromagnetic phenomena. Electromagnetic force is the interaction between charged particles. Lorentz's force is also known as the electromagnetic force. The electromotive force refers to the amount of work required by a battery pack to move charged particles through an electrical circuit. An electromagnetic field is a natural field caused by the motion of an object which is electrically charged. It affects ... Read More

Introduction Dimension of area place an important role in the measurement process. Measurement is the most valuable part of science. Also, it is most important for living too. Measurement plays a crucial role in our lives. It is the foundation for all technological development. The accuracy of measurement is more important in science. Metrology is the comparison of any physical quantity with its standard quantity. The measurement method is essentially to measure a quantity, it is always compared to a standard quantity. A unit is defined as a physical quantity having a definite numerical value accepted by a rule or ... Read More

Introduction Diffusion rate shows how fast the process of diffusion take place. The net migration of particles from a region of high concentration to one of low concentration is referred to as diffusion, which is a physical phenomenon. Diffusing substances might be solids, liquids, or gases. Similar to this, any of the three physical states could potentially be present in the medium where diffusion takes place. The airborne movement of ammonia gas serves as an illustration of this. Similar to how nitrogen gas would swiftly diffuse into the atmosphere if a liquid nitrogen canister had a small leak. ...

Introduction Diffusion and concentration process are fascinating phenomenon in the science field. It is a visible process in the physical world. The study of diffusion processes started in the 19th century. The spreading of the fragrance of flowers is the best-known example of this process. This process involves the random movement of substances such as atoms, ions, molecules, etc. from a region of higher concentration to a lower concentration. It always requires a concentration gradient that is a difference in concentration. The number of particles present in the total volume or a given volume is the concentration. For a ... Read More
