What is Electronic Switch in Oscilloscope?: The electronic switch is a device that enables two signals to be displayed simulÂtaneously on the screen by a single gun CRT. The basic block diagram of an Electronic…
What is Electron Volt? The joule (J) is the unit of energy in the SI system. In some engineering power problems this unit is very small, and a factor of 103 or 106 is introduced…
What is Electron Emission? The liberation of electrons from the surface of a substance is known as electron emission. For electron emission, metals are employed because they have many free electrons. In a metal like…
What is Electromechanical Chopper?: Electromechanical Chopper - An ac amplifier must see ac in order to perform useful work. A fair number of chopping and modulation techniques are available to change direct current, or to…
What is Electrolytic Process and Basic Principle of Electrolysis The fact that electrical energy can produce chemical changes and the processes based on it, called the 'electrolytic process', are widely used for the extraction of…
What is Electroforming Process? - Definition and Applications Reproduction of objects by electrodeposition on some sort of a mould or form is known as electroforming. This is another application of electrodeposition. In the reproduction of…
What is Electrodes? - Definition, Types, Applications and Advantages An electrode is a piece of wire or rod (of a metal or alloy), with or without flux covering, which carries current for welding. At one…
What is Electric Traction? - Introduction, Definition, Working, Advantages and Disadvantages Electric traction was first introduced in Britian in the year 1890 at 600 V dc using third rail for urban and suburban services. For…
What is Electric Heating and its Advantages? Heating is required for domestic purposes such as cooking and heating of buildings, as well as for industrial purposes such as melting of metals, hardening and tempering, caseÂhardening,…
What is Dual Power Supply? -Circuit Diagram and its Workings? Many discrete and ICs need bipolar (dual power supply or ± V) supplies. This can be easily accomplished with two three-terminal regulators, as illustrated in…
