Vacuum Triode, Construction and Working: Construction of Vacuum Triode - The construction and the schematic symbol used for a vacuum triode are illustrated in Fig. 5.8. It, as the name…
What is Vacuum Diode, Construction, Working and Applications: Construction of Vacuum Diode - Vacuum diode is the simplest form of the electron tube for the production and control of free…
What is Photoelectric Emission and Laws of Photoelectric Emission?: When the surface of certain alkaline material such as sodium, potassium, cesium or rubidium is illuminated by a beam of light…
What is Secondary Emission? When a beam of high velocity electrons suddenly strikes a metallic surface, they give up their kinetic energy to electrons and atoms which they strike. Some…
What is Active Components and Passive Components? All electronic circuits, however complicated, contain a few basic components (generally speaking, only five)—three passive and two active components. Though passive components by…
Frequency Generating Transducer: Frequency Generating Transducer - Unlike variable parameter analog transducers, frequency and pulse generating transducers measure physical variables in terms of a pulse repetition rate. Since frequency is…
Air Blast Circuit Breaker: Air Blast Circuit Breaker - It is not possible to produce a low resistance arc without a considerable gas pressure so that the only type available…
Color Picture Tube Working: A Color Picture Tube Working requires correct sweep currents, input voltages and drive voltages. Having said this very quickly, it is now a good idea to…
