Velox Boiler - Construction, Working Principle and Advantages: Velox Boiler - When the gas velocity exceeds the sound velocity, the heat is transferred from the gas at much higher rates…
What is a Power Converter? Solid-state power converter are employed for obtaining the appropriate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most…
Light Activated SCR (LASCR) - Symbol, Construction and Operation: Light activated SCR is just an ordinary SCR except that it can also be light triggered. Most LASCRs also have a…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
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…
Crystal Oscillators - Circuit, Working, Advantages and Disadvantages: In crystal oscillators, the usual electrical resonant circuit is replaced by a mechanically vibrating crystal. The crystal (usually quartz) has a high…
What is Oscillator? - Types of Oscillators: An oscillator is the basic element of all ac signal sources and generates sinusoidal signals of known frequency and amplitude. It is one…
Miller Sweep Circuit and Miller Bootstrap Sweep Circuit: The basic R-C sweep circuit is shown in Fig. 30.134, in which opening of switch S provides sweep voltage, as already explained…
