(D) angular displacement of an axis fixed to the rotor with respect to a synchronously rotating axis. Answer: (D) 8. A band-limited signal with a maximum frequency of 5 kHz is to be sampled. According to the sampling theorem, the sampling frequency in kHz which is not valid is (A) 5 (B) 12 (C) 15 (D) 20 Answer (A) 9. For a periodic signal v(t) 30 sin 100 t 10 cos 300 t 6 sin(500 t ), 4 p = + + + the fundamental frequency in radians/s is (A) 100 (B) 300 (C) 500 (D) 1500 Answer (A) 10. A bulb in a staircase has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and also can be turned OFF by any one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles (A) an AND gate (B) an OR gate (C) an XOR gate (D)a NAND gate Answer (C) 17. A single-phase transformer has no-load loss of 64 W, as obtained from an opencircuit test. When a short-circuit test is performed on it with 90% of the rated currents flowing in its both LV and HV windings, he measured loss is 81 W. The transformer has maximum efficiency when operated at (A) 50.0% of the rated current. (B) 64.0% of the rated current. (C) 80.0% of the rated current. (D) 88.8% of the rated current. Answer: (C) 18. A single-phase load is supplied by a single-phase voltage source. If the current flowing from the load to the source is 10 150 A Ð − ° and if the voltage at the load terminals is 100 60 V Ð ° , then the (A) load absorbs real power and delivers reactive power. (B) load absorbs real power and absorbs reactive power. (C) load delivers real power and delivers reactive power. (D) load delivers real power and absorbs reactive power. Answer: (B) 19. A source s v (t) V cos 100 t = p has an internal impedance of ( ) 4 j3 . + W If a purely resistive load connected to this source has to extract the maximum power out of the source, its value in W should be (A) 3 (B) 4 (C) 5 (D) 7 Answer (C) Last edited by Neelurk; April 2nd, 2020 at 10:00 AM. |
