ELECTRICAL ENCYCLOPEDIA

What is Inverter Technology?   What is inverter technology? Is inverter technology for me? If you are a consumer that wants to save energy, money on your electricity bills and make the environment a better place then inverter technology is the right choice for you. Most people tend to turn off their air conditioner units at the wrong time just to save on their electricity bill. The previous, is completely understandable considering the economic events we are going through in today’s world.  continue.. How Inverter Works in Airconditioner?   An inverter in an air conditioner is used to control the speed of the compressor motor to allow continuously regulated temperature. By contrast, traditional air conditioners regulate temperature by using a compressor that is periodically either working at maximum capacity or switched off entirely. Inverter-equipped air conditioners have a variable-frequency drive that incorporates an adjustable electrical inverter to control

What is Induction Cooking?   Induction cooking uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove. To be used on an induction cooktop, a cooking vessel must be made of a ferromagnetic metal, or placed on an interface disk which enables non-induction cookware to be used on induction surface. In an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food. While the current is large, it is produced by a low voltage. continue.. Advantage and Disadvantages of Induction Cooker   To serious cooks, the most important favorable point about induction cookers--given that they are as or more "powerful" at heating

AC Power Plugs Definition   AC power plugs and sockets are devices for removably connecting electrically operated devices to the power supply. Electrical plugs and sockets differ by country in voltage and current rating, shape, size and type of connectors. The types used in each country are set by national standards. Generally the plug is the movable connector attached to an electrically operated device's power cord, and the socket is a fixture on equipment or a building structure. Plugs have male circuit contacts, while sockets have female contacts. The plug has protruding prongs, blades, or pins that fit into matching slots or holes in the socket. A wall-mounted socket is also called a receptacle, outlet, or power point. It is enclosed by a cover variously called a wall plate, face plate, outlet cover,socket cover, or wall cover.  continue.. Basic Types of Electrical Plugs   When using a grounding adapter, always attach the U-shaped piece of metal on the adapter to the screw

What is Nanorobotics?   Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometer (10−9 meters). More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components. The names nanobots, nanoids, nanites, nanomachines or nanomites have also been used to describe these devices currently under research and development. continue.. How Nanobots will work?   In this article, we'll learn about the potential applications of nanorobots, the various ways nanorobots will navigate and move through our bodies, the tools they will use to heal patients, the progress teams around the world have made so far and what theorists see in the future. In the next section, we'll learn about the conditions and diseases nanorobots will treat in the future. continue..

Electric Fruits Project   The purpose of this project was to find out which fruit would generate enough electricity to light a light bulb and to discover which fruit would light the bulb the longest. To conduct my experiments I used a Multimeter, copper and zinc wires & electrodes, alligator clips with leads, various light bulbs and five types of fruits. continue.. Why Do Citrus Fruits Produce Electricity?   In order to generate electricity, there must be a power source and a complete circuit. When using a citrus fruit to create electricity, these rules still apply. In a simple experiment using a citrus fruit, the components of the circuit include: a lemon or other fruit, wire, two different metal elements and a small light bulb. The lemon in this circuit serves as the battery and power source. continue.. Fruit Power Project   Purpose To demonstrate how an electrical current can be generated using citrus fruits (such as lemons or limes) that is strong enough to power a small

What is Electricity?   Electricity is a general term encompassing a variety of phenomena resulting from the presence and flow of electric charge. These include many easily recognizable phenomena, such as lightning, static electricity, and the flow of electrical current in an electrical wire. In addition, electricity encompasses less familiar concepts such as the electromagnetic field and electromagnetic induction. continue.. Who First Discovered Electricity?   The history of electricity goes back more than two thousand years, to the time the Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two. By the 17th century, many electricity-related discoveries had been made, such as the invention of an early electrostatic generator, the differentiation between positive and negative currents, and the classification of materials as conductors or insulators. In the year 1600, English physician William Gilbert conned the term electric, from the Greek elektron

Who is Heinrich Rudolf Hertz?   Heinrich Rudolf Hertz (February 22, 1857 – January 1, 1894) was a German physicist who clarified and expanded the electromagnetic theory of light that had been put forth by Maxwell. He was the first to conclusively prove[1] the existence of electromagnetic waves by engineering instruments to transmit and receive radio pulses using experimental procedures that ruled out all other known wireless phenomena. continue.. Heinrich Rudolf Hertz as an Inventor   His name also became the term used for radio and electrical frequencies: hertz (Hz), as in kilohertz (kHz) or megahertz (MHz). The hertz designation has been an official part of the international metric system since 1933. Before Hertz gained professorships in Karlsruhe and Bonn, he had studied under the famous scientist Hermann von Helmholtz in Bonn, and it was Helmholtz who encouraged Hertz to attempt to win the science prize that led to some of Hertz's most important discoveries. From 1885 to 18
