Question
```how does bode plot have an advantage over root locus? how
does it determine the stability of a system depending upon
the location of poles and zeroes?```

Re: how does bode plot have an advantage over root locus? how does it determine the stability of a system depending upon the location of poles and zeroes?
# 1
Bode plot measures out Gain Margin and Phase Margin. Gain
margin gives the value of gain you can adjust to bring back
the system to stable (in case system is unstable) or gain
upto which you can adjust without affecting the system
stablitiy.

# 2
usually root locus is to know how the system closed loop
poles vary when a particular parameter of the system is
varied( generally parameter is choosen is gain). the plot is
located in s plane. in bode plot gain vs frequency is
plotted for a particular k(gain) value. so gain is adjusted
with respect to frequency in bode plot.

  Question Asked @ Answers Other Electrical Engineering Interview Questions What is the Frequency while we step up the voltage from 220V to 11KV? Is it possible? Explain it? 2 why use generator Earthing/Graunding. 4 What is surge impedence and surge loading....??? 1 why do we use magnetic contactors ?circuit breakers are not enough? 5 what is the purpose of using battery in dg sets, please specify in details. Balco 2 pls give proper discription of selection of transformer based on particular load. 1 what is the working principle of electrical motors? 4 How to work star delts method in the case of single phase motor? Siemens 4 can we synchronize star system generators with delta system generators? 1 what is demagnetising effect & crossmagnetising effect and how it is related to electrical system?is there any more effects are available or only these two?? Telco 1 WHY HUMMING SOUND OCCURED IN HT TRANSMMISSION LINES? 6 Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer? 2 For more Electrical Engineering Interview Questions Click Here
