The MHD generation or, also known as magneto hydrodynamic power generation is a direct energy conversion system which converts the heat energy directly into electrical energy, without any intermediate mechanical energy conversion, as opposed to the case in all other power generating plants. Therefore, in this process, substantial fuel economy can be achieved due to the elimination of the link process of producing mechanical energy and then again converting it to electrical energy.History of MHD

What is a Power Plant?A power plant (also known as a power station or power generating station), is an industrial location that is utilized for the generation and distribution of electric power on a mass scale. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power (these are also known as an alternator). The relative motion between a magnetic field and an electrical conductor creates an electric current.These are gen

Electrical energy is a form of energy that results from the movement of electrons from one point to another in a conductor. It is a secondary energy source, meaning that it is derived from other primary sources of energy, such as fossil fuels, nuclear power, solar power, wind power, hydropower, etc. These primary sources of energy can be converted into electrical energy by various methods, depending on their nature and availability. In this article, we will explore the main sources of electrical

A thermoelectric generator (TEG) is a device that converts heat energy into electrical energy using the Seebeck effect. The Seebeck effect is a phenomenon that occurs when a temperature difference exists between two different conductors or a circuit of conductors, creating an electric potential difference. TEGs are solid-state devices that have no moving parts and can operate silently and reliably for long periods of time. TEGs can be used to harvest waste heat from various sources, such as indu

An electrical symbol is a small image used to represent an electrical or electronic device or function. They are also known as circuit symbols or schematic symbols as they are used in electrical schematics and diagrams.Some basic electrical symbols include: Wires Diode Batteries Transformers Capacitors Resistors Inductors Fuses Switches Bipolar Junction Transistors Electromagnetic RelaysThere are many electrical and circuit symbols used internationally around the world. While they are mostly st

Transformers are one of the most common types of electrical devices, and they may be found in a variety of applications within the area of electrical engineering, including power systems. Therefore, in the position of an electrical engineer, it is usually neededto compute various characteristics of a transformer in order to establish the circumstances under which it operates. In order to do this,will need to use conventional equations, which can be seen mentioned in the sections that will follow

Another important property in AC electronic circuits, besides resistance and inductance, is capacitance. Capacitance is measured in units. The unit of capacitance is the farad. While inductance is represented in a circuit by a coil, capacitance is represented by a capacitor. In its most basic form, the capacitor is constructed of two parallel plates separated by a nonconductor, called a dielectric. In an electrical circuit, a capacitor serves as a reservoir or storehouse for electricity.Capacita

Lenz's Law, named after the Russian physicist Heinrich Lenz (1804-1865), is a fundamental principle in electromagnetism. It states that the direction of the induced electromotive force (emf) in a closed conducting loop always opposes the change in magnetic flux that caused it. This means that the induced current creates a magnetic field that opposes the initial change in magnetic flux, following the principles of conservation of energy.Understanding Lenz's Law allows us to appreciate the science

Here's a good wayto define electromagnetism -Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is responsible for electromagnetic radiation such as light.Who Discovered Electromagnetism?In 1820, the Danish physicist, Hans Christian Oersted, discovered that th

What is a Multimeter?A multimeter (MM) is essential for those working with electronics or electrical systems. It is a versatile instrument that combines several measurement functions into one unit, making it indispensable for electricians, technicians, and even DIY enthusiasts. This article will explore a multimeter's features, types of multimeters, and useswhile answering some common questions about this indispensable tool.Multimeters come in two primary forms: digital (DMMs) and analog multime
