Switching Diode in Electronics: In discussing the rectifier diodes, the importance of reducing the reverse-bias current and the power losses under forward bias to the minimum was emphasized. But in case a junction diode is…
What is Crystalline Structure? What is Crystalline Structure? - Solids are characterized by incompressibility, rigidity and mechanical strength. This indicates that the molecules, atoms or ions that make up a solid are closely packed, i.e.,…
Nonlinear Circuits Interview Questions and Answers: 1. What is a comparator and where is it used ? Ans. A comparator is essentially an op-amp operated in open-loop configuration. The output signal is either a high or…
Zero Sequence Current Relay: This type of zero sequence current relay is similar to that of negative phase sequence relay as discussed in article Induction Type Negative Phase Sequence Relay. The relay is made to…
Induction Motor Speed Control Methods: The only way to control the speed of a synchronous motor is to control the input frequency and voltage such as to keep V/f constant. The Induction Motor Speed Control,…
Frequency Shift Keying Demodulator Working (FSK): In digital data communication, binary data is transmitted by means of a carrier frequency. It uses two different carrier frequencies for logic 1 and logic 0 states of binary…
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…
Overhead Construction for Tramways, Trolley Buses and Railways: As we know already that, for trams, trolley buses and for railways operating at 1,500 V and above overhead contact wire is used. The design of overhead…
Difference between Brushless DC permanent magnet motor and Conventional motor: The difference between Brushless DC permanent magnet motor and Conventional motor is given below 1. In the same frame, for same cooling, the brushless PM…
Grounding of Impulse Testing Laboratories: An earth or ground system means an established stable .reference potential normally taken to be zero. There are three types of Grounding of Impulse Testing Laboratories are: the ideal ground,…
