MPPGCL JE Electrical Mock Test - 10 - Electrical Engineering (EE) MCQ

According to the information given in the question, we can draw the following diagram.

Thus we can see if a man has to travel to point E from point A  (through these points by the shortest distance), he has to follow a path point A → B → F → E.

Thus travelling from point A, he will pass the first point B.

Hence, the correct answer is "Point B".

The sentence "They will have completed the work by the time we get there" in the Active Voice can be transformed into the Passive Voice as:

A. The work will have been completed by the time we get there.

This option accurately represents the original sentence in the Passive Voice, maintaining its intended meaning.

One word substitution is Cynic.
Egoist: a self-centered or selfish person
Fatalist: one who accepts all things and events as inevitable.
Stoic: a person who can endure pain or hardship without showing their feelings or complaining.
Cynic: a person who believes that people are motivated purely by self-interest rather than acting for honourable or unselfish reasons.

As we know that ,
Mansion is a very big house, while hovel is a small, dingy house, castle is a large fortified residence.
Hence , hovel is an opposite word of Mansion . 

As we can say that ,
Tractable is something that can be managed easily, i.e., manageable.
From above it is clear that Unmanageable is opposite word of Tractable . 

• Lump sum: a single payment made at a particular time, as opposed to a number of smaller payments or installments.
• Strong: having the power to move heavy weights or perform other physically demanding tasks.
• Little: small in size, amount, or degree.
• Huge: extremely large; enormous.
• Massive: exceptionally large.

So, the synonym of Massive is Huge.

Freedom available to Indian citizens:
- Freedom to criticise the government
- Freedom to reside in any part of the country
Freedom not available to Indian citizens:
- Freedom to participate in armed rebellion
Explanation:
- Indian citizens have the freedom to criticise the government. This means they have the right to express their opinions, voice their concerns, and hold the government accountable for its actions and policies.
- Indian citizens also have the freedom to reside in any part of the country. They can choose to live and work in any state or union territory without any restrictions.
- However, the freedom to participate in armed rebellion is not available to Indian citizens. Engaging in armed rebellion or taking up arms against the government is considered a criminal act and is punishable under the law.
Conclusion:
In summary, Indian citizens have the freedom to criticise the government and the freedom to reside in any part of the country. However, they do not have the freedom to participate in armed rebellion.

Introduction:
Basket weaving, pottery, and other handicrafts are examples of traditional crafts that have been practiced for centuries. These crafts are often produced on a small scale and are typically made by individual artisans or small groups of artisans. They are considered to be part of the cottage industry.
Explanation:
Cottage industries are small-scale, decentralized manufacturing businesses that are typically run from the homes of the workers. These industries often rely on manual labor and traditional techniques to produce handmade goods. Basket weaving, pottery, and other handicrafts are perfect examples of cottage industries because:
1. Handmade production: These crafts are typically made by hand using traditional methods and techniques. Each piece is unique and reflects the skill and creativity of the artisan.
2. Small-scale production: Basket weaving, pottery, and other handicrafts are usually produced in small quantities. The production process is often labor-intensive and time-consuming, making it difficult to scale up production.
3. Local sourcing of materials: Artisans often source their materials locally, such as using locally grown fibers for basket weaving or clay from nearby sources for pottery. This not only supports local economies but also adds uniqueness to the products.
4. Artistic expression: Handicrafts are often regarded as an art form, allowing artisans to express their creativity and cultural heritage through their work. These crafts carry a sense of tradition and are deeply rooted in local culture.
5. Market demand: Handicrafts have a niche market, with consumers appreciating the authenticity and uniqueness of these products. They are often sought after as decorative items or as gifts.
Conclusion:
Basket weaving, pottery, and other handicrafts are prime examples of cottage industries. They embody the traditional craftsmanship, artistic expression, and cultural heritage of a region. These industries provide opportunities for artisans to showcase their skills and contribute to the local economy while preserving traditional techniques and knowledge.

By applying the current division rule

In order to find Norton resistance R_N, open circuit the terminals A and B and replace the current source by an open. Then resistance at open-circuited terminals A and B is R_N.

Linear bilateral network

If the induced emf in the stator of an 8 pole induction motor has a frequency of 50 Hz and that in the rotor is 1.5 Hz, at what speed is the motor running and what is the slip?

Slon: f = 50 Hz and fr = 1.5 Hz,

Ns = 120f/p = 120 x 50/8 = 750 rpm

We have fr = sf

Hence s= fr/f = 1.5/50 = 0.03

Hence N = (1- s)Ns = (1- 0.03) x 750 = 727.5 rpm

Single phase induction type energy meter is also popularly known as watt-hour meter. This name is given to it. This article is only focused about its constructional features and its working. Induction type energy meter essentially consists of following components

1. Driving system

2. Moving system

3. Braking system and

4. Registering system

Cold Reserve It is that reserve generating capacity which is not in operation but can be made available for service.

Hence, the correct option is (C)

LVDT is a linear variable differential transformer which is an inductive transducer and converts the displacement of the core to electrical energy and also is an electromechanical device.

Hence, the correct option is (B).

A potentiometer is defined as a 3 terminal variable resistor in which the resistance is manually varied to control the flow of electric current. A potentiometer acts as an adjustable voltage divider.

PTC stands for "Positive Temperature Coefficient". PTC thermistors are resistors with a positive temperature coefficient, which means that the resistance increases with increasing temperature.

With NTC thermistors, resistance decreases as temperature rises. An NTC is commonly used as a temperature sensor or parallel with a circuit as an inrush current limiter.

Hence, the correct option is (A)

Slon: f = 50 Hz and fr = 1.5 Hz,

Ns = 120f/p = 120 x 50/8 = 750 rpm

We have fr = sf

Hence s= fr/f = 1.5/50 = 0.03

Hence, the correct option is (A)

Mass action law states that at thermal equilibrium, the productof number of holes and number of electrons in a semiconductor are constant and is independent of donor and acceptor impurity doping (only intrinsic concentration is considered).

V_m = I_m x R = 5mA x 2.2kΩ = 11 V
∴ v(t)=11 sin (2π×100t+45^∘)V
At t=0.4ms, v=11 sin[2π×100]
(0.4×10^-3)+45^∘]V
=11sin (0.2513rad+45^∘)
= 11 (14.4^∘ + 45^∘)
= 9.47 V

The lower resistance has the high voltage. That means the highest resistance has the highest voltage drop.

In series circuits, the resistor with the greatest resistance has the greatest voltage drop. Since the current is everywhere the same within a series circuit, the I value of ΔV = I • R is the same in each of the resistors of a series circuit.

Hence, the correct option is (D)

The stator rotating magnetic field is rotating at Ns. The current-carrying rotor conductor also produces a rotor magnetic field of speed Ns.

Therefore, the stator rotating magnetic field and rotor rotating magnetic field rotate at the same speed N_s in the air gap. They are stationary with respect to each other and make the rotor rotate at speed N. This happens at any slip.

Hence the correct option is A

=

Capacitor factor = load factor x utilisation factor.

If the centrifugal switch of a single-phase resistance split centrifugal switch of a single-phase resistance split induction motor does not open after starting of motor, the motor will draw high current and get over-heated.

Leakage flux in a transformer occurs because air is not a good magnetic insulator.

Because phase sequence of the network upto point F₁ will be less than upto point F₂.
