Re: KSEB PSC Question Papers
On your demand I will get the PSC, AE (Electrical Stream) exam paper of Kerala State Electricity Board. Here is the exam paper 1) The CPU of a computer consists of None of the above Memory and ALU INPUT and OUTPUT Unit ALU and Control Unit 2) The capacitance connected between the I/P and O/P of an amplifier affects its high frequency response due to MILMAN effect MILLER effect COLPIT effect COLLINS effect 3) Which instrument is used to measure low values of resistance ? Maxwell Bridge Kelvin Double Bridge Wheatstone Bridge Anderson Bridge 4) An ideal OP-AMP has infinite gain infinite input impedance infinite bandwidth all of the above 5) The number of flip flops required in a decade counter is 3 4 10 2 6) For stability and economic reasons we operate the transmission line with power angle in the range 10° to 25° 65° to 80° 60° to 75° 30° to 45° 7) The transfer function is defined for Linear and time-variant system Linear and time-invariant system Non-linear and time-variant system All of the above 8) A dc cumulatively compounded motor delivers rated torque at rated speed. If the series fields is short circuited then the armature current and speed will decrease and increase respectively both increase increase and decrease respectively both decrease 9) The collector current of transistor is always less than emitter current none of the above greater than emitter current equal to emitter current 10) Which one of the following is not an image file format ? image.png image.pdf image.jpg image.bmp 11) When resonance occurs in a circuit, the pf is 1 less than 1 0 greater than 1 12) Two devices commonly used to generate light for fiber optic communication system LED and LCD LED and TFT All of the above LED and ILD 13) While drawing the phasor diagram of a parallel circuit, which one is taken as the reference None of the above Voltage Power Current 14) A voltmeter gives 120 oscillations per minute when connected to the rotor of an induction motor. When the stator frequency is 50Hz, slip of the motor is 5% 4% 2.5% 2% 15) Steady state stability of a power system is improved by reducing fault clearing time single pole switching using double circuit line decreasing generator inertia 16) Base modulation is used in TV transmission because All of the above Large power O/P and better efficiency High degree of linearity Power required is small 17) The most commonly used detector in AM receiver is Coherent detector Ratio detector Discriminator Envelope detector 18) Which one of the following is a synchronous optical network ? TELNET INTERNET DELNET SONET 19) The Hall effect voltage in intrinsic silicon changes sign on application of magnetic field is positive is zero is negative 20) The value of coefficient of coupling is always greater than 1 none of the above equal to 1 less than 1 |
