ECIL Placement Paper Technical - Electronics OIST, Bhopal-26 Dec 2010
Hi I'm Manish Kumar Ahirwar. I gave the ECIL exam for EE on 26 December, 2010. My branch is Electrical. Name of the post: Graduate Engineer Trainee (Electrical) Duration: 2 hours No. of question: Only 50 (Technical only) 1 question= 3 marks Negative marking: 1/3 rd There are no question from Aptitude, GA. So question paper was based on technical based Some question are. Which turbine used for low head (kaplan, pelton etc.) * Two x-mer a & b have 50hz and 400hz frequency. Which is big a or b * What is the use of ready signal in 8085 up * Two lamp connected in series than total power drawn? * What is unit of flux density? * What is the ratio of magnetic field intensity to flux density? * One question from synchronous motor * Calculate Rth of given ckt? * Two questions from thevnin theorem * What is use of MOV? * Calculate the frequency of parallel Resonance ckt? * One question from OPAM (calculate o/p voltage)? * Calculate load current of Bridge rectifier? * One program on C? * Which diode made by metal& semiconductor? * Which sensor not used for measurement of wight? (capacitor, strain gauge, piezoelectric) * Which GATE used as a Comparator( OR, AND, EX-OR, None of these) * One question from Lagging-leading? * Calculate the Laplace of te^-at? * Given a characteristics equation of stable system find value of a? * When we used a negative feed back in Oscillator? * Which is used for amplification purpose (Ans. Transistor) * In CE configuration why Capacitor used parallel with resistor of emitter? * If sin i/p is given in vertical plate of CRO and nothing on horizontal what will happen? * Calculate the Time constant of RC ckt * If sinusoidal ip is given to schimit trigger what will be output? * Calculate the RMS value of given voltage? * Filter roll off characteristics on the basis of active/passive, order, type of components?
