    Hi All, these are some of the memory based questions from BHEL exam 2010 held on 31st  OCT 2010. There are in total 240 questions asked and time is 2 and half hour with 0.2 negative marking. I hope this will help you guies for your next preparation.

    1) A compensating coil in wattmeter helps in providing
    (a) decrease impedance in current coil (b) decrease in impedance in pressure coil (c) voltage drop in pressure coil two more options are there i think answer should be (d) please check.
     
    2) Which of the following is transfer type ac-dc (1) electrostatic (2) electrodynamic and so on (b) is right answer.
     
    3) When three phase unbalanced supply system in transmission system then
    Ans: Only negative sequence fault exist
     
    4) Then ask about Maxwell bridge
    Ans: L is in series with R
     
    5) Laplace transform of sin (q) is
    Ans:  w/(s2+w2)
     impulse response of 1/(s+1)(s+2)
     
    6) Two very simple questions on thevenin where two resistor connected in parallel and a voltage source and across one of the resistor find out Vth and Rth
     
    7) Then ask about network topology where a node is connected with three branches and two branches have current 5A and 10A find out third branch current.
     
    8) Some portion of simple mathematics ask like find out eigen value where given a matrix [5  3 ]   
    Ans is (6,4)
     [ 3  -3]
    Also ask about maxima f(x)= x-0.5x2  ans is 0.5
     
    9) What is phase cross over frequency of k/s(s+1)(s+2)
     
    10) Sumpner's test in transformer is for detecting no load losses.
     
    11) House hols fan has which type of motor ans is capacitor start and run induction motor.
     
    Friends several questions are numerical based that i never attempted as time is not more to understand and solve
     
    120 questions from technical and 120 from aptitude were asked.
     
    In aptitude 1,3,6,10,15 what is 21st term
     
    Some questions so much difficult some very easy but it requires speed try to catch easy questions and solve within seconds.
     
    Verbal reasoning they asked about statement conclusion, spell check, logic reasoning like tree: Trunk then pen: ink and
     
    Venn diagram for e.g.
     
    1) Men, parents, mother 
    2) Atmosphere, gases, nitrogen
    Here you have to find relation between them and which venn diagram suitable for it will be the option. 
    In english passage, spotting the error, antonyms
     
    All the best!
