Pergunta feita para Senior Maintenance Engineer...2 de junho de 2014

Is 3,599 a prime number? Yes or No. Explain.

10 respostas


3599 = 3600-1 = 60^2 - 1^2 This is known as "difference of two squares" Which factors into (60-1)*(60+1) Therefore factors are 59 and 61 A longer, more general method is to say that you only need to check primes less than the square root of 3599, which again because its 60^2 - 1 you can just try primes less than 60. Menos

3600 = 60^2 Sqrt(3600 - 1) = 60 -/+ 1 >>> 59 x 61

Immediately, i got a call from them next day... If u didn't get get a call from them within 2 days.. then u r disqualified from the selection process Menos

It depends on the position level you applied for ... If it was entry level....probably there will be no technical questions..they will discuss with you the experience, summer training & courses you had before... I strongly recommend to focus on the HR typical & common questions if the position level is Entry Level.. bcoz they are seeking for certain traits on the character of every candidate Menos

Actually, I applied for 2 positions Wireline Engineer and Maintenance Engineer. I passed the 1st HR interview and have been invited for a Technical interview next week. I am an Entry level however they told me it will be Technical Interview with the Manager and I am curious to know the type of technical questions that he might ask about for the same position that you applied for “Entry Level Maintenance Engineer”? In addition, to the expected Salary? Menos

why in transformer oil is used?

3 respostas

In order to insulate and to provide cooling to the windings we use transformer oil. Transformer oil has very high breakdown voltage so that it does not breakdown inspite of having high voltage coils around it. When transformer works on high load its winding temperature increases hence oil temperature also increases which then cooled through the cooling tubes having contact with outside air. Menos

Cooling purpose , transformer oil is insulation oil also

Called as also insulation oil and this is stable at high temperatures.
