The increasing demand of electricity cannot be met through conventional ways of generating electricity. To fulfil the electricity demand, several new methods have been developed. Solar panels are one of the most common of them. A solar panel is a semiconductor device that can convert sunlight into electricity. This light to electricity conversion is based on the principle of photovoltaic effect. Thus, solar panels are also known as photovoltaic systems. In a solar panel, there are multiple PV or solar cells used that absorb the sunlight and produce electricity. This electricity is stored in rechargeable batteries and supplied as per ... Read More
Introduction In early times sunlight was used for the bleaching of substances. Charles Tennant in the year 1799 introduced a solid combination of chlorine and slaked lime. This is the major contributor to the production of a bleaching powder in bulk. Now it is available in many commercial products, and it is used for the bleaching of water that is to remove germs present in water. And in some chemical industries, it is used as an oxidizing agent. Sodium Hydroxide or caustic soda is also an important inorganic chemical compound that is found in many commercial products such as soap, ... Read More
This article is meant for explaining the two most widely used visual representations of electrical systems also called electrical diagrams. These diagrams are single-line diagram and multiline diagram. These two diagrams are used in electrical engineering to represent various electrical layouts and connection arrangements of electrical systems. In electrical engineering, the visual/graphical representation of electrical systems like distribution systems, control panels, transmission line, generating stations, etc. is very important to understand the connections of various system components, designing and analyzing electrical systems, and more. In the field of electrical engineering, the following two main types of visual representations are ... Read More
Introduction Hydrocarbon butane has the chemical formula 𝐶4𝐻10. At room temperature, it exists in a gaseous state and is an alkane. Edward Frankland, a British chemist, was discovered in 1849. Although Edmund Ronalds, an English industrial chemist, noted its numerous qualities. He discovered butane in oil products and researched its qualities. Butane belongs to the family of paraffinic hydrocarbons and is a colourless, odourless gaseous hydrocarbon (compound of carbon and hydrogen). Normal butane, also known as n-butane, is a molecule in which all the carbon is connected in a straight chain. Isobutane, on the other hand, has a branched chain. ... Read More
A smart meter is an electrical instrument used for measuring electrical energy consumed and other electrical parameters of the electricity supply system. It is basically a type of energy meter equipped with more advanced metering technologies. The main advantage of using a smart meter is that it does not require any manual reading system for billing and other purposes. Instead, it can automatically send the data through communication channels to the electricity company. Therefore, smart meters help in reducing the operational cost and time. In this article, we will explain the major advantages and disadvantages of smart meters. Before ... Read More
Introduction $\mathrm{CaCO_{3}}$ is found within oyster shells. It’s found in naturally occurring forms such as aragonite, vaterite, & calcite, & industrial forms such as limestone, marble, chalk, & travertine, & oyster shells. It's an active component in agricultural lime, which is formed when calcium ions combine with carbonate ions in hard water to generate lime scale. It has medicinal use as a calcium supplement or an antacid, but excessive ingestion can be harmful & lead to bad digestion. What is Calcium Carbonate? It's an inorganic complex with the formula $\mathrm{CaCO_{3}}$. It's a chemical complex that is among the first chemical ... Read More
An inverter battery is an electrochemical device that is used for storing electrical energy. It is a type of rechargeable battery that works with an inverter to provide continuous power supply in the case of main supply outages. An inverter battery charges when main power supply is available and it delivers the stored electrical power when the main power supply is disrupted. In this article, we will explain the different types of inverter batteries along with their advantages and disadvantages. But before that let us get an overview of inverter batteries and know about their specifications. What is ... Read More
Introduction Calcium would be a necessary element for all living organisms. Calcium sulphate found natively in limestones. Calcium sulphate seems to be an inorganic substance made up of $\mathrm{CaSO_{4}}$ as well as related hydrates. It is now utilized as a desiccant in form of λ-anhydrite. One distinct hydrate is known as plaster of Paris, whereas all the other exists plainly as a result of such mineral gypsum. All types resemble white solids that are insoluble in water. Water becomes permanently hardened due to calcium sulphate. Natural gypsum production in the world is roughly 127 million tonnes per year. However, it ... Read More
This article is meant for explaining different types of electric vehicles, their construction, components, working principle, and features. A type of vehicle, a car, or a bike, or any other, that uses electricity as the source of energy to run is called an electric vehicle. Today, electric vehicles are becoming one of the most popular modes of transportation because of their sustainability, low operating cost, and eco-friendliness. Traditional vehicles operating on petrol and diesel have very high operating cost and they also pollute the environment due to emissions. Till date, several different types of electric vehicles have been ... Read More
Introduction Acidic and basic compounds are always fascinating things for scientists at that time. The colour change experiment using litmus paper is commonly used for the identification of the strength of acid and bases. But it does not give proper data on the acidity and basicity of chemical compounds. The proper identification of the acidity of a chemical compound is very necessary. In the year 1909, the chemist Søren Sørensen introduced the concept of pH from the old theories that are prevailing at that time. He also introduced the pH scale which is a breakthrough of certain theories present at ... Read More
