MPPGCL JE Electrical Mock Test - 9 - Electrical Engineering (EE) MCQ

From the options given, it can be guessed that the parts labelled P, Q, R, S can be ordered to form a meaningful sentence as
It is easier → for men→ to venture into space → than to explore→beneath their feet.
so order is QPSR.

From the final arrangement, we get, R doesn’t belong to that group as except for R, all the others are facing outside.
Hence, Option D is correct.
References:
Q sits second to the right of P.
Inferences:
From the above reference, we get two different cases:
In case 1, P sits at the corner or in the middle of the side of the table.

References:
R is not an immediate neighbor of P.
R faces inside.
R sits third to the left of W.
Inferences:
From the above references, we get different cases for R, in case 1(a) in which R faces P and in case 1(b) R faces Q.

References:
T sits third to the left of U.
V sits second to the left of U.
Inferences:
So, from this case 1(b) and case 2 will be eliminated as there is no possible place for V in these cases after placing U and T. Hence, we get our final arrangement in which S sits on the immediate left of P and V sits on the immediate right of R.
Final arrangement:

Checking Statement I:

Using the above references, we get the information:
 
_ > _ > _ > _ > Tarak > _

Vijay > Komal > Rishi

Here, we cannot merge the above inferences to form a single arrangement of the order of heights of these persons.

So, we cannot say who among these persons is the tallest.

Hence, data in statement I alone is not sufficient.

Checking Statement II:

Using the above references, we get the information:

Rishi > Tarak/Sanjay

So, we cannot say who among these persons is the tallest.

Hence, data in statement II alone is not sufficient.

Checking Statements I and II:

Using the above reference, we get the following arrangement:

Usha > Vijay > Komal > Rishi > Tarak > Sanjay

Clearly, both statements I and II together are sufficient to answer the question.

Hence, Option D is correct.

Given Statement: P < Q < R < S = T

Conclusion:

I. Q < T → True (As, Q < R < S = T → Thus, it is clear that Q < T. So, the conclusion is true)

II. P > S → False (As, P < Q < R < S → Thus, it is clear that P < S. So, the conclusion is false)

III. R = T → False (As, R < S = T → Thus, it is clear that R < T. So, the conclusion is false)

Hence, the correct answer is "Only conclusion I follows".

The passive voice of imperative sentences which suggest order, suggestion or request can be made in two ways:

Active: Verb + object

Passive:

Let + object + be + past participle
You are requested/ ordered/ suggested + to + verb (Ist form) + object
Going by first way of passive voice, the passive voice of the given sentence would be: Let the door be shut.

Esteemed means regarded with respect, honored, prestigious

The esteemed panel discussed crucial issues on a televised debate

The esteemed judge ruled in the favor of convict due to lack of evidence

After two years of discussion and debate they came out with one of the finest constitutions the world has ever had. This constitution gave to its citizens the most extensive rights available in any country. Together, they decided that in the search for a solution to the problems, nobody should be excluded, no one should be treated as a demon.

What is meant by the term 'constituency'?
A constituency refers to a specific area or region from where voters elect a representative to the Lok Sabha or Vidhan Sabha. It is an essential concept in the democratic electoral system. Here are the key points to understand about constituencies:
1. Definition: A constituency is a geographically defined area that represents a specific group of voters who have the right to elect a representative to a legislative body.
2. Representation: Constituencies ensure that every region or area is represented in the legislative body. Each constituency has its own representative who acts as a voice for the concerns and interests of the people in that particular area.
3. Electoral Process: During elections, voters from a constituency cast their votes to elect a candidate who will represent their interests and concerns. The candidate who receives the highest number of votes becomes the elected representative for that constituency.
4. Delimitation: Constituencies are often delimited or redrawn periodically to ensure fair representation based on population changes. This process is carried out by an independent authority to maintain equal representation among constituencies.
5. Lok Sabha and Vidhan Sabha: In India, constituencies are primarily associated with the Lok Sabha (the lower house of Parliament) and Vidhan Sabha (the state legislative assembly). Each state is divided into different constituencies, and voters from each constituency elect their representatives to these bodies.
In conclusion, a constituency is a specific area from where voters elect their representatives to the Lok Sabha or Vidhan Sabha. It ensures fair representation and gives people the opportunity to choose their leaders based on their concerns and interests.

The sentence "We must respect the elders" in the Active Voice can be transformed into the Passive Voice as:

A. The elders must be respected.

This option accurately conveys the original meaning of the sentence in the Passive Voice.

In 2-wattmeter method. For all power factors between 0.5 to 1 both wattmeter’s show +ve reading.

Brushes Commutator both

Measurement of Three Phase Power by Three Wattmeters Method

The circuit diagram is shown below-

The resultant sum of all the readings of wattmeter will give the total power of the circuit. Mathematically we can (P = P₁P₂P₃ = V₁I₁V₂V₂V₃I₃)

In a plasma application (Helium or Argon Plasma), we would like to measure the current. The voltage is around 10kV AC and modulated with a function generator.

Hence, the correct option is (D)

Hence, the correct option is (B)

- air capacitor is also called as “Gang capacitor”. A gang capacitor is a combination of two or more variable capacitors mounted on a common shaft to. This adjustment allows simultaneous change in capacitance of grouped capacitors.

Load factor

So, in the diversity factor, the rate is fixed.

The diversity factor is defined as the ratio of the sum of the maximum demands of the various parts of a system to the system’s coincident maximum demand. The maximum demands of the individual consumers of a group do not occur simultaneously.

Hence, the correct option is (A)

-> For a semi-enclosed zero-sequence or rewirable fuse which employs copper as the fuse element, the value of the fuse factor is usually 2. Lower values of fusing factor can be employed for enclosed cartridge fuse, which uses silver or bimetallic elements.

Hence, the correct option is (A)

Improving the power factor means reducing the phase difference between voltage and current since the majority of loads are inductive; they require some amount of reactive power for them to function. The capacitor provides this reactive power or bank of capacitors installed parallel to the load.

Hence, the correct option is (A)

A negative coefficient for a material means that its resistance decreases with an increase in temperature. Semiconductor materials (carbon, silicon, germanium) typically have negative temperature coefficients of resistance.

Hence, the correct option is (C)

M = 5.1H

Here multiplier factor m.f. = 4

Actual power = mf x meter reading

= 4 x 2000 = 8000 W

(Req = R₁|R₂)

= 2000 X 2000/2000 + 2000

Req = 1000Ω

P = P₁ + P₂ = 2 + 2 = 4W

The leakage reactance is reduced when the primary and secondary winding of the transformer are wound on top of each other.
