### Why Network Rail and why the rail industry?

They give you a map with switches and relays. They correspond to track signaling systems. Standard red orange green. KVL, KCL and decent circuitry knowledge. Less

Just try to relate safety measures/hazards/etc to previous work experience. There was a relay on a circuit diagram. Just know what it is and basic functionality. Less

thank you mate, how about the KVL and KCL? what sort of questions were you asked about in regard? Less

### Why railway industry? Why Network Rail? How do you develop the professional relationship and how do you feel before during and after?

Show your expectation to the company and tell them how you going to make a contribution Less

Hey mate, please share the technical questions, if you can.. Thank you so much

I was not asked any obvious technical question.

### In trouble shooting if you are not finding the fault what you will do?

ask to my senior on duty

I will ask my duty commander

I will check with relax mind. I hope i will fix it.

### Q: What does a capacitor look like at high frequency?

A: A capacitor looks like a capacitor, inductor, and resistor in series at high frequency. Less

A short

Its an short circuit at very high frequencies. Look at the impedance for a capacitor and you'll notice that the frequency is inversely related to it. (also note that capacitor impedance is purely reactive). Therefore, as frequency increases the impedance approaches 0, which acts like a short. (an inductor is the opposite) Less

### A boat is in a swimming pool and there is a rock in the boat. What happens to the level of water if the rock is thrown out of the boat?

Any rock that will have the density less than water?... It will fall because due to Achimedes' Law the total bouyant force decreased, hence so it is with the volume of space occupied below the water level. Less

It depends on the ratio of volume of the rock vs the displacement of water. This is dependent on the density of the substance. In the boat it should displace a volume of water greater than the volume of the rock since the density of the rock is greater than the density of the water. Once in the water it should displace only it's own volume which do to it's density is less than the water it had to displace while in the boat.; hence, the water level decreases. Less

It depends on the density of the rock If the rock sinks: the water level actually falls....think about it...but this is the right answer. Less

### 1. Tell me a time when you are handling new problems. 2. What is the inspiration for the career you chosen? 3. Tell me a time when you are doing something that is not required.

Hey did u attend the second interview? or did u fail in the first interview? My interviewer told me I would get the second interview in 4 weeks...but I did not get any rejection or acceptance after the campus interview.. Less

I am still waiting for their notifications...

How did you come to know that you didn't get offer,any email,call ?and when did your application got updated? Less

### what is your marks (%age) in last semester?

I have answered what i have got.

82.88% in 10th and 73% in diploma

I’m pursuing my engineering from G H Raisoni Collage Of Engineering, Nagpur , Maharashtra, I’m studying in 3rd in Electrical Engineering and my self Vishal Deshmukh .. I have 68% in 10th because I represent Maharashtra in National Kabbadi Turnament so that reason behind my low percentage in 10th and my pointer from 5th sem is 8.20 and SGPA from 2nd year is 8.89 so I can eligibal for your company Less

### How would you know if an electric motor is bad without connecting to power?

Explain the motor resistance test.

Motor resistance test:This test is an important measurement/test because it detect some of the problems other test/measurement couldn't, it is easy with the use of "motor circuit analysis" winding resistance test detects various faults in motors such as shorted and open turns, wrong turn count, wrong wire gauge, some connection mistakes, resistance balance between phases, short to ground. Less

Aside the physical observation for burnt and smell of the coil also the colour appearance of the coil and rust, an ammeter will be used to check winding of the phase to determine if there short circuit or shunt in each winding,which implies continuity . The cone or ammiture should be tested ,component test for resistivity and inductance will be tested. Less

### What represents P, in P=IV

Watts

Power

Current times voltage = power (watt)
