Fuel Handling System and Ash Handling System: Handling of coal: The coal handling is divided into two types: Out-plant handling. In-plant handling. 1. Out-plant handling: This handling includes the handling of coal from coal mine…
What is Electropolishing, Electrotyping, Electrofacing, Electrometallisation and Anodizing Closely allied to bright dipping is electropolishing, which utilises anodic treatment in specially formulated electrolytes to bring up a polished surface on such metals as stainless steel.…
Armature Resistance Control Method of DC Motor: In this armature resistance control method of speed control, reduced speeds are obtained by inserting resistance in the armature circuit. It may be employed with series, shunt and…
Resistance Start Single Phase Induction Motor: It is a form of split-phase motor having a high resistance connected in series with the auxiliary or starting winding, as illustrated in Fig. 1.38 (a). A typical torque-speed…
BJT Bias Circuit Troubleshooting: Voltage Measurement - When a BJT Bias Circuit Troubleshooting is constructed in a laboratory situation, the supply voltage (VCC) and the voltage levels at the transistor terminals (VC, VBÂ and VE) should…
Magnetic Circuit Calculations: Normally magnetic circuit calculations involve two types of problems. In the first type of problem it is required to determine the excitation (mmf) needed to establish a desired flux or flux density…
Semiconductor Temperature Sensing Diode: Semiconductor Temperature Sensing Diode is a versatile device and finds use in many applications. Two of its parameter, that is forward voltage drop (Vf)Â and reverse saturation current (Is)Â are temperature sensitive. The…
Types of Insulators in Transmission Lines: The overhead line conductors should be supported on the poles or towers in such a way that currents from conductors do not flow to earth through supports i.e., line…
Waveguide Coupling: When waveguide pieces or components are joined together, the Waveguide Coupling is generally by means of some sort of flange. The function of such a flange is to ensure a smooth mechanical junction…
Shifted Unit Step Function: This Shifted Unit Step Function is defined by the equation for a step function which changes abruptly at the time t = + a. In general, the step function has unit…
