What is Thyristor? - Thyristor Family and its Applications Thyristor is the general name given to a family of semiconductor devices having four layers with a control mechanism, although this…
Junction Field Effect Transistor (JFET) - Construction, Symbols and Operation: Depending upon the majority charge carriers, Junction Field Effect Transistor (JFET) have been classified into two types, namely (i) N-channel…
Tuned Base Oscillator - Definition and Working Principle: When a parallel tuned L-C circuit is placed in the base-to-ground circuit, the oscillator is known as the tuned base oscillator. The…
Transistor Construction: The transistor construction consists of a silicon or germanium (preferably silicon because of its smaller cutoff current ICBO, smaller variations in ICBOÂ due to variations in temperature and higher…
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.…
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…
Construction of Vacuum Tetrode, Working and Applications: Tetrode means four, hence tetrode is a four electrode tube consisting of a cathode, a control grid, a screen grid, and a plate.…
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…
