Madhya Pradesh Power Transmission Corporation Limited is going to conduct the written examination for the Jobs of Junior Engineer & Executive Trainee posts


About the Examination :

The question paper consists of four sections. All parts contains equal number of questions. Each question is of one marks.

Test Sections :-

Reasoning
General Awareness
Aptitude
Electrical Cadre Questions


Negative Marking - The will be no deduction of marks for each wrong answer.

Q.1 To calculate Thevenin‟s equivalent value in a circuit
(A) all independent voltage sources are opened and all independent current sources are short circuited.
(B) both voltage and current sources are open circuited
(C) all voltage and current sources are shorted.
(D) all voltage sources are shorted while current sources are opened.

Ans: D
To calculate Thevenin‟s equivalent impedance value in a circuit, all independent voltage sources are shorted while all independent current sources are opened.

Q.2 A 26 dBm output in watts equals to
(A) 2.4W. (B) 0.26W. (C) 0.156W. (D) 0.4W.

Ans: A
A 26dBm output in watts equals to 0.4 W because
10*log10(400MW/1MW) = 26DB

Q.3 The Characteristic Impedance of a low pass filter in attenuation Band is
(A) Purely imaginary. (B) Zero. (C) Complex quantity. (D) Real value.

Ans: A
The characteristic impedance of a low pass filter in attenuation band is purely imaginary.

Q.4 The real part of the propagation constant shows:
(A) Variation of voltage and current on basic unit.
(B) Variation of phase shift/position of voltage.
(C) Reduction in voltage, current values of signal amplitude.
(D) Reduction of only voltage amplitude.

Ans: C
The real part of the propagation constant shows reduction in voltage, current values of
signal amplitude.

Q.5 The purpose of an Attenuator is to:
(A) increase signal strength.
(B) provide impedance matching.
(C) decrease reflections.
(D) decrease value of signal strength.

Ans: D
The purpose of an Attenuator is to decrease value of signal strength.

Q.7 In a transmission line terminated by characteristic impedance, Z
O
(A) There is no reflection of the incident wave.
(B) The reflection is maximum due to termination.
(C) There are a large number of maximum and minimum on the line.
(D) The incident current is zero for any applied signal.

Ans: A
In a transmission line terminated by characteristic impedance, Zo there is no reflection of the incident wave.

Q.8 For a coil with inductance L and resistance R in series with a capacitor C has
(A) Resonance impedance as zero.
(B) Resonance impedance R.
(C) Resonance impedance L/CR.
(D) Resonance impedance as infinity.
Ans: B
For a coil with inductance L and resistance R in series with a capacitor C has a
resonance impedance R.
