MPPGCL JE Electrical Mock Test - 4 - Electrical Engineering (EE) MCQ

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see W is not good in Mathematics but good in Hindi.

Hence, the correct answer is "W".

As the result of Race is Fatigue similarly the result of Fast is Hunger.

During that time Lenin introduced the idea of a socialist, cooperative economy and emphasized collectivisation .Hence, these values inspired Indians to set up a socialist economy.

There are four main agents of erosion. Moving water, wind, gravity, and ice wear away or break up rocks, sediments, and soil from the land's surface. When these materials are deposited or dropped in new places, it is called deposition. Erosion and deposition work together.

Hence, Option A is correct.

Checking → statement I:

References:

P is married to U.

V is married to R.

Q is the husband of W.

S is the daughter-in-law of W.

Inferences:

From the above references, we can conclude the following:

So, we can’t conclude the relation between X and S.

Thus, statement I alone is not sufficient to answer the question.

Checking → statement II

References:

V is the father of Q.

U is the mother-in-law of Q.

T is the sibling of X.

T is unmarried.

Inferences:

From the above reference, we can conclude the following:

So, we can’t conclude the relation between X and S.

Thus, statement II alone is not sufficient to answer the question.

Checking → statement I and II:

References:

P is married to U.

V is married to R.

Q is the husband of W.

S is the daughter-in-law of W.

V is the father of Q.

U is the mother-in-law of Q.

T is the sibling of X.

T is unmarried.

Inferences:

From the above references, we can conclude the following:

So, we can conclude that X is the husband of S.

Thus, statement I and II together is sufficient to answer the question.

Hence, option D is correct.

From the common explanation, we can say that R sits 3rd to the right of the one who sits immediate right of M. 
Hence, Option D is correct.
Final Arrangement:

Common Explanation:
References:
Only two boys sit to the left of J.
Eight boys sit between R and J.
Only three boys sit between R and M.
Inferences:
From the above references, we get two different cases:

References:
P sits fourth to the right of R.
O sits third to the left of M.
Inferences:
So, from this case 2 will be eliminated as P sits fourth to the right of R.

References:
Only three boys sit between O and H.
T sits third to the right of M.
V sits fourth to the right of O.
More than 12 boys sit between P and H.
More than seven boys sit between P and J.
Inferences:
From the above reference, we get the final arrangement:

Hence, Option B is correct.

The logic follows here : 
1. Sukhoi Su-30MKI is a Fighter Jet.
2. INS Vikrant is different from these two, it is an Aircraft Carrier.

The least possible Venn diagram for the given set of words is :

Hence, the correct answer is "Option (4)".

Additional Information

INS VIKRANT

• INS Vikrant is a 37,500-tonne carrier and has been launched almost four-and-a-half years after its keel was laid.
• The launch of warship, which has a length of 260 metres and is 60 metres wide.
• The launch has marked India's entry into a select club of countries capable of designing and building a carrier of this size and capability.
• There are 14 decks in all, including five in the superstructure. The ship has over 2,300 compartments, designed for a crew of around 1,700 people, including specialized cabins to accommodate women officers.
• There are 14 decks in all, including five in the superstructure. The ship has over 2,300 compartments, designed for a crew of around 1,700 people, including specialized cabins to accommodate women officers.

Sukhoi Su-30MKI

• The Sukhoi Su-30MKI is a twinjet multirole air superiority fighter developed by Russia's Sukhoi and built under license by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
• The IAF has nearly 260 Su-30MKIs in inventory as of January 2020.
• Based on the Su-30 fighter aircraft, Su-30MKI is equipped with thrust vectoring control and canards.
• The aircraft has a length of 21.9m, wingspan of 14.7m and a height of 6.4m.
• The maximum take-off weight of Su-30MKI is 38,800kg.
• The Su-30MKI is also equipped with a N011M passive electronically scanned array radar, OLS-30 laser-optical locator system and Litening target designation pod to guide air-to-surface missile and laser guided munitions.
• The Su-30MKI is armed with a 30mm Gsh-30-1 cannon with 150 rounds of ammunition.
• The Su-30MKI fleet of IAF was fitted with air-launched version of BrahMos supersonic cruise missiles and was successfully tested in November 2017.
• The BrahMos can strike targets within the range of 290km.
• The IAF completed the successful integration of the cruise missile on the fighter, with the third live firing of the missile from the aircraft in December 2019.

While making a short-circuit test, low-voltage winding is always short-circuited and measurements are made on the high-voltage winding. If measurement is made on the low-voltage winding, the -current will be inconveniently low.

Both hysteresis and eddy current losses depend upon A. maximum flux density B_m in the core and B. supply frequency f. Since transformers are connected to constant voltage and constant-frequency supply, both B_m and f  are constant. Hence iron or core losses in a transformer are practically the same at all loads.

Damper bars in case of salient pole rotors of hydro alternators are usually inserted in pole faces to damp out the rotor oscillations during transient state owing to sudden change in load conditions.
The damper winding comes into play only during rotor hunting, when rotor speed departs from synchronous speed.

Hence, the correct option is (D)

Hence, the correct option is (B)

From the circuit drawn,

{{chart?cht=tx&chl=\(2I+2(I-I}}

and {{chart?cht=tx&chl=\(I}}

Then,

Energy stored in magnetic field is given by,

= 2 X 10 = 20 V

K=190/910=19/91 ;

Hence, the correct option is (B)

delta to star conversion,

Hence, the correct option is (B)

PMMC reads average value.
Vavg = area/(time period)
From given waveform
Vavg = (10*4)/16 = 2.5 Volts
PMMC rectifier will read rms value = 2.75 Volts
MI reads true rms value
Vrms = (peak value)/2 (for square wave)
= 10/2 = 5V
