Flux Linkage of n Parallel Conductors Carrying Current: As shown in Fig. 2.5, consider a group of n parallel conductors carrying current I1, I2 ,..., In whose sum equals zero. Distances of these conductors from…
V Shift and I Shift Method: V Shift and I Shift Method - A voltage source with a passive branch in series with it is called an accompanied voltage source. Similarly a current source with…
Distributed Control System: Distributed Control System - Since the beginning of process control in late 1970s, it has made great progress in every control activity. Similar to the other electronic equipment, its size is decreasing…
Capacitor Coupled Common Base Amplifier: A practical Capacitor Coupled Common Base Amplifier (using a plus/minus supply) is shown in Fig. 12-39. [Note the polarity of the input coupling capacitor (C1).] The CB circuit is analysed…
Electronic Instruments (Analog as well as Digital) Interview Questions and Answers: 1. Why ordinary voltmeter cannot be used in electronic circuits? Ans. A moving coil voltmeter draws a large current, hence a large power from the…
Algorithm for Short Circuit Computation: So far we have carried out short circuit calculations for simple systems whose passive networks can be easily reduced. In this section we extend our study to large systems. In…
Different types of losses in transformer: The transformer has no moving parts so that its efficiency is much higher than that of rotating machines. Different types of losses in transformer are enumerated below: Core Loss…
Polyphase AC Motors for Traction Drives: Polyphase AC Motors for Traction Drives - Advantages of ac motors over dc we already know. Because of negligible maintenance, ruggedness and higher power per unit weight or volume,…
