well , I am feeling HAPPY to answer your question , I would like to suggest you to access the source site if its available , for more information.Since the advent of power electronics, it has become difficult to draw a boundary between electrical and electronic devices. An approximate boundary can be drawn on the basis of the power level 20 watts can be set for this purpose.Those devices operating

Electronics is the study of the flow of charge through various materials and devices such as semiconductors, resistors, inductors, capacitors, nano-structures and vacuum tubes. Although considered to be a theoretical branch of physics, the design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer

well, ,In electronics, a vacuum tube, electron tube inside North America, thermionic valve, or just valve elsewhere, especially in Britain, is a device used to amplify, switch, otherwise modify, or create an electrical signal by controlling the movement of electrons in a low-pressure space, often tubular in form. Many devices called vacuum tubes are filled with low-pressure gas: these are so

A negative voltage is determined by how the circuit reacts to either hole flow, or electron flow. A hole is an absense of an electron, a "home" for an electron of sorts, and it has a positive potential. An electron has a negative potential. They are drawn to each other.A negative voltage means the electrons are going the other way to the way your voltmeter things they should go, turn you

well,Electronics refers to the flow of charge electron through non-metal conductors often called semi-conductors, where as electrical refers to the flow of charge through metal conductors. For example, flow of charge through silicon which is not a metal would come under electronics whereas flow of charge through copper which is a metal would come under electrical. This distinction started around

The cathode ray tube CRT is an evacuated glass envelope containing an electron gun a source of electrons and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted.The electron beam is deflected and modulated in a way which causes it to display an image on the screen. The image may represent

well gauri, Electronic Commerce means buying and selling of goods and services across the internet. An e commerce site can be as simple as a catalog page with a phone no, or it can range all the way to a real time credit and processing site where customer can purchase downloadable goods and receive them on the spot. The meaning of electronic commerce has changed over the last 30 years. Originally

the laser action.In solid state lasers, an electrical current pumps electrons into the laser medium - typically a semiconductor - exciting electrons that are fixed in the medium. Driven into higher energy states, a condition known as a population inversion, the excited electrons quickly decay back into lower energy states, releasing the excess energy as photons. Carefully positioned mirrors bounce photons

e-commerce is the online transaction of business, featuring linked computer systems of the vendor, host, and buyer. Electronic transactions involve the transfer of ownership or rights to use a good or service. Most people are familiar with business-to-consumer electronic business B2C. Common illustrations include Amazon.com, llbean.com, CompUSA.com, travelocity.com, and hotels.com.E-commerce can

usually refers to the interaction involving only the electrons of an atom. The Compton effect was observed by Arthur Holly Compton in 1923 and further verified by his graduate student Y. H. Woo in the years the Compton scattering. Comptons experiment convinced physicists that light can behave as a stream of particles whose energy is proportional to the frequency.The interaction between electrons and high energy

Power cycling an electronic device is a technical way of saying "resetting" it. When you power cycle a device, you turn it off and then turn it back on again. Pretty high-tech, huh? Usually, you should let the device sit for a couple seconds after turning it off to make sure the memory in the device is fully cleared before turning it back on.Any electronic device can be power cycled

that are now being used on new models.Technically speaking, CRTs are vacuum tubes. Images are created when a beam of electrons scans back and forth across the back of a phosphor-coated screen. The cathode ray tube CRT is an evacuated glass envelope containing an electron gun a source of electrons and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons.
