Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound for three phases and identical…
Power BJT - Construction, Operation and its Characteristics: Power transistors are large-area devices. Because of differences in geometry and doping concentrations, their properties tend to vary from those of the small-signal devices. The structure of…
Selection of Ratings of Devices of a Chopper Converter: Chopper Converter - The waveforms of currents and voltages are useful in deciding the ratings of devices. The main thyristor carries the load current. Superimposed on…
Voltage Regulation Formula of Transformer: Voltage Regulation Formula - Constant voltage is the requirement of most domestic, commercial and industrial loads. It is, therefore, necessary that the output voltage of a transformer must stay within…
Differential Pilot Wire Protection: The Differential Pilot Wire Protection is based on the principle that under normal conditions, the current entering one end of a line is equal to that leaving the other end. As…
What is Analog Signal and Digital Signal? What is Analog Signal and Digital Signal? - In communication systems, a signal means a time varying electriÂcal signal which contains all information or intelligence. The anaÂlog signal…
Working Principle of Digital pH Meter | Block Diagram: Working Principle of Digital pH Meter - The Digital Measurement of hydrogen ion activity (pH) in a solution can be accomplished with the help of a…
Current Divider Equation: In a parallel circuit, the Current Division in all branches. Thus, a parallel circuit acts as a current divider. The total current entering into the parallel branches is divided into the branches…
Difference Between Thyristor and Transistor: As already mentioned, transistors and thyristors are both semiconductor devices. They are now widely employed in switching operations because of their numerous advantages such as noiseless operation owing to absence…
Output Stage of an Op Amp and its Voltage Transfer Characteristics: The output stage of an op amp is another requirement which should have very small output impedance and provide the external load current so…
