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
An energy meter is a device used for measuring the amount of electrical energy consumed by a load over a certain period of time. This device is essential for recording the electricity usages so that consumers can monitor and change the energy consumption patterns to reduce energy consumption and hence the bill amount. An energy meter is an important link between power supplier and consumers that allows them for efficient measurement of electricity supplied or consumed. What is an Energy Meter? An electrical device or instrument which is used for measuring the amount of electricity consumed by the consumers over ... Read More
Introduction Carbohydrates seem to be a type of naturally occurring carbonyl molecule containing many — 𝑂𝐻 groups. This might also include their derivative products, which also lead to the synthesis of certain compounds when hydrolyzed. Sugars include carbohydrates with a sweet taste that could be water-soluble. Carbohydrates constitute abundant substances in the plant as well as animal cells. Carbohydrates contained inside skeletal bones serve as food reserves for plants, arthropods, or even mammals. All of those are significant energy resources that are required for a range of metabolic activities; the energy would be provided via oxidation. What are Carbohydrates? The ... Read More
An alternator is an electromechanical energy conversion device that converts mechanical energy into alternating current electrical energy. An alternator is basically a synchronous generator that produces electricity at a certain frequency. To drive the alternator, a prime mover is used. Some commonly used prime movers are steam turbine, water turbine, gas turbine, and diesel engine. Like any other rotating electrical machine, different types of faults can also occur in an alternator. Due to these faults, we get a reduced efficiency and performance of the alternator. Further, these faults can cause malfunctioning or complete failure of the alternator that imposes ... Read More
