Re: Question paper of BSNL JTO
BSNL or Bharat Sanchar Nigam Limited recruits every year JTOs exam basically in three major categories, Telecom, Civil and Electrical. This exam usually held in the last week of June. You want previous year BSNL JTO question paper of Electrical Engineering so here I am giving you same: Electrical Engineering SECTION-I QUESTION NUMBER 1-20 CARRY 1 MARK EACH 1. The main scale of a vernier calliper is ruled in 1 mm units. The vernier scale is 49 mm long and divided in 50 units. The resolution of the vernier calliper is a. 0.002 mm b. 0.005 mm c. 0.01 mm d. 0.02 mm 2. A frequency counter with a gating time of 50 ms counts 1254 cycles of an input square wave. The frequency of the input wave is a. 39.87 Hz b. 62.70 Hz c. 1.254 kHz d. 25.08 kHz 3. A data acquisition system with the input range of ± 5.0 V has a 12-bit ADC in it. The resolution of the system is approximately a. 0.24 mV b. 0.48 mV c. 1.22 mV d. 2.44 mV 4. Wattmeters are based on the principle of a. permanent magnet moving coil meter b. electrodynamic meter c. electrostatic meter d. moving iron meter 5. The resolution of a Gray-coded optical shaft encoder with 10-bit output is approximately a. 0.098° b. 0.176° c. 0.225° d. 0.352° 6. If y(t) Y(s) indicates a Laplace transform pair, then y(t) for t0 when 2 3 3 2 3 s e Y s s s 7. The undamped natural frequency in rad/s and the damping ratio of the system with the transfer function 2 2 64 12 100 s G s s s are, respectively, a. 10 and 1.2 b. 10 and 0.6 c. 8 and 1.2 d. 8 and 0.75 8. The gain at the breakaway point of the root locus along the real axis of a unity feedback system with the transfer function 2 1 K G s s s is a. K = 0 b. K = 0.5 c. K = 1 d. K = 1.25 9. Gain margin of the unity feedback system with the loop transfer function 3 100 1 G s s is a. 35.35 b. 12.5 c. 0.08 d. 0.03 10. The discrete time system with the transfer function 3 2 1 0.4 0.25 0.1 G z z z z is a. stable b. unstable c. marginally stable d. sustained oscillatory For full question paper I am uploading a pdf file it is free to download: |
