Common Source Circuit Analysis: A FET Common Source Circuit Analysis is shown in Fig. 11-Â6. With the capacitors treated as ac short-circuits, the circuit input terminals are the gate and source, and the output terminals…
Protective Devices and Interlocks: Protective devices must be incorporated in the control circuit (or circuits) to interrupt the flow of current to the motor to guard against overloads or other conditions dangerous to the motor…
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 term is most commonly applied…
Paper Mill Process: The raw materials for Paper Mill Process undergo two processes before the paper is available: The pulp is made from the raw materials. This pulp is converted to paper in paper making…
Miller Effect in Amplifier Frequency Response: According to this effect, when viewed from the input base terminal of the CE-connected transistor the capacitance Ccb appears as (1 - Av)Ccb i.e., it is amplified by a factor of…
Bus Impedance Matrix Method for Analysis of Unsymmetrical Shunt Faults: Bus Impedance Matrix Method of fault analysis, given for symmetrical faults  can be easily extended to the case of unsymmetrical faults. Consider for example an…
Self Excited DC Generator: Rather than arranging a separate dc source for excitation purposes, practical generators are always excited from their own armature terminals, this method of excitation being known as Self Excitation. A Self…
RC Driving Point Impedance function: As the name indicates, the RC networks consist of only R and C components. There is no inductor in RC networks. The RC Driving Point Impedance function is denoted as…
What is Bearing? - Definition and Types of Bearings: Bearings are those parts of a machine which house supports and restrain the rotating parts. The moving part of the bearing is known as journal and…
Directional Relays: Selective protection cannot be achieved with time graded overcurrent protection systems in ring or loop systems as well as in radial circuits with two end power supply. A directional feature is incorporated in…
