Is 3,599 a prime number? Yes or No. Explain.
10 Answers↳
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. Less
↳
(N+A)(N-A)=N^2-A^2
↳
3600 = 60^2 Sqrt(3600 - 1) = 60 -/+ 1 >>> 59 x 61

why in transformer oil is used?
3 Answers↳
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. Less
↳
Cooling purpose , transformer oil is insulation oil also
↳
Called as also insulation oil and this is stable at high temperatures.
Tell me about a time you are face with a difficult situation, How did you solve it? Given a room with 3 light bulbs which have their respective three switches (On/Off) outside the room.

If you take one at a time once there there on remove one wire or off but you have to turn power on again you should find which switch belongs to the bulbs. Less
