Electron Beam Welding - Working Principle, Advantages, Disadvantages and Applications: Basically, electron beam welding in vacuum utilises the kinetic energy of electrons travelling with high velocity in a high vacuum (10-3 to 10-5 mm Hg). When the electrons…
Electromechanical Energy Conversion via Electric Field Energy: Electromechanical energy conversion via the electric field is analogous to the magnetic field case studied earlier. Charge in the Electric Field Energy is analogous to flux linkages and…
Electromechanical Breakdown and Thermal Breakdown: Electromechanical Breakdown:When solid dielectrics are subjected to high electric fields, failure occurs due to electrostatic compressive forces which can exceed the mechanical compressive strength. If the thickness of the specimen…
Electromechanical AD Converter: Another area of application in which Electromechanical AD Converter is very important, involves the translation of the angular position of a shaft into digital information. (A very common application of this type…
Electromagnetic Spectrum: In an earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself; some of this was seen in the preceding…
Electromagnetic Relay - Definition, Construction and Working Principle: Electromagnetic Relay - A relay, in the general sense of the word, is any apparatus which serves to actuate or control the regime of a high power…
Electromagnetic Interference: To control ON/OFF operation of ac devices we can use electromagnetic relay. This relay has both normally open and closed contacts. When a current is passed through the coil of the relay, the…
Electromagnetic Induction Relay - Structure and Working Principle: Electromagnetic induction relay operate on the principle of induction motor and are widely used for protective relaying purposes involving a.c. quantities. They are not used with d.c.…
Electromagnetic Attraction Relay - Working Principle and its types: Electromagnetic attraction relay operate by virtue of an armature being attracted to the poles of an electromagnet or a plunger being drawn into a solenoid. Such…
Electrolytic Processes Interview Questions and Answers: 1. What is electrolysis ? Ans. The breaking of a substance (known as electrolyte) into ions by flow of electric current through it is known as electrolysis. 2. What…
