Compound Semiconductor Materials: Most of the compound semiconductor materials are formed from the combinations of group III and group V elements. A portion of the periodic table listing the more…
Thyratron Working Principle: Thyratron is a hot cathode gas filled triode. Normally it is filled with a small amount of inert gas such as argon, hydrogen, neon or mercury vapour.…
Construction of Phanotron: The constriction of a gas-filled diode or phanotron is similar to a vacuum diode except that the size of its electrodes is larger so as to conduct…
Classification of Gas Filled Tubes: Vacuum tubes are no doubt, extensively used in communication control and industrial electronic circuits, but these can carry small plate currents (typically from 1 mA…
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 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 Resistor in Electronics? What is Resistor in Electronics? - Resistance is a dissipative element, which converts electrical energy into heat, when the current flows through it in any…
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…
