MPPGCL JE Electrical Mock Test - 1 - Electrical Engineering (EE) MCQ

The Zimbabwe African National Union-Patriotic Front has been the ruling party in Zimbabwe since independence in 1980. The party was led for many years under Robert Mugabe, first as Prime Minister with the Zimbabwe African National Union and then as President from 1987 after the merger with the Zimbabwe African People's Union and retaining the name ZANU–PF, until 2017 when he was removed as leader.

The correct answer is Markanda.

Key Points

• Aruna is the ancient name of Markanda river.
  • ​The Markanda river flows in Sirmaur district, Ambala district, and Markanda town in Kurukshetra district.

  • The Markanda river originates from the Shivalik hills.
  • The total length of the river is 120 km out of which 90 km is in Haryana.
  • A barrage at Jalbehra in Kurukshetra district has been built on the river.
  • The Begna river is the main tributary of the Markanda river.

Important Points

• The Sahibi River originates in Jaipur Distt. of Rajasthan and it passes through Alwar Distt. 
  • It drains into the Yamuna at Delhi, where its channelled course is also called the Najafgarh drain, which also serves as Najafgarh drain bird sanctuary.
• The Ghaggar River rises in Shivalik hills in the Solan district of Himachal Pradesh.
  • It enters Haryana from the Panchkula district.
  • And at the end, the river leaves Sirsa District of Haryana State and reaches Sri Ganga Nagar district, Rajasthan.
  • Kaushalya river is a left bank tributary of Ghaggar River.
• Yamuna River is the largest tributary of the Ganga River.
  • It originates from Yamunotri Glacier.
  • It meets the Ganges at the Sangam (where Kumbh Mela is held) in Prayagraj, Uttar Pradesh after flowing through Uttarakhand, Himachal Pradesh, Haryana and Delhi.
  • Length: 1376 km
  • Important Dam: Lakhwar-Vyasi Dam (Uttarakhand), Tajewala Barrage Dam (Haryana) etc.
  • Important Tributaries: Chambal, Sindh, Betwa and Ken.

All these words represent the inhabitants of India.

Hence, "Printer" is the correct answer.

Important PointsInput Device: A piece of equipment/hardware that helps us enter data into a computer is called an input device. For example keyboard, mouse, etc. 

1. Keyboard:

• A simple device comprising keys and each key denotes either an alphabet, number, or number commands which can be given to a computer for various actions to be performed
• It has a modified version of typewriter keys
• The keyboard is an essential input device and computers and laptops both use keyboards to give commands to the computer

2. Joy Stick:

• It is a device that comprises a stick that is attached at an angle to the base so that it can be moved and controlled
• Mostly used to control the movement in video games
• Apart from a computer system, a joystick is also used in the cockpit of an aeroplane, wheelchairs, cranes, trucks, etc. to operate them well

3. Scanner:

• This device can scan images or text and convert it into a digital signal
• When we place any piece of a document on a scanner, it converts it into a digital signal and displays it on the computer screen

Output Device: A piece of equipment/hardware that gives out the result of the entered input, once it is processed (i.e. converts data from machine language to a human-understandable language), is called an output device. For example printers, monitors, etc. 

Printer:

• A device that makes a copy of the pictorial or textual content, usually over a paper is called a printer
• For example, an author types the entire book on his/her computer and later gets a printout of it, which is in the form of paper and is later published
• Multiple types of printers are also available in the market, which can serve different purposes

As, 123 → 13²

As, 235 → 25³

The middle digit of first term becomes power to the next term.

⇒ (2/1000) × (5/10)

⇒ (10/10000)

⇒ (1/1000) = 0.001

∴ 0.002 x 0.5 = 0.001

Reverse saturation current (IS) of diode increases with increase in the temperature, the rise is 7%/ºC for both germanium and silicon and approximately doubles for every 10ºC rise in temperature. Thus if we kept the voltage constant, as we increase temperature the current increases.

For more watt bulb, less resistance will be there so, the length of that bulb will be lower.

The magnetic flux density, B is related to the magnetic flux intensity, H as,
B=μ∘H+M
where πμ_∘=4π×10^-7H/m is the permeability in free space, and M=X_m H is the magnetization of the material, and X_m is the magnetic susceptibility.
Hence,

The surge impedance for a lossless line is when r=o and g=0 is

Tank circuit consist of a pure inductor and pure Capacitor connected in parallel.

Hence, the correct option is (B)

For 100 watts bulb, R= 200×200/100 = 400 ohms

For 50 watts bulb, R= 200×200/50 = 800 ohms

So 50 watts bulbs will glow brighter.

Hence, the correct option is (B)

A base load station supplies almost a constant load throughout the day i.e. for 24 hours. Therefore, more efficient plants are used as base load stations.

Hence, the correct option is (D).

Hence, the correct option is (A).

Permeability,

μ₀ = B/H = (ØA)/ (I / 2πr)

= (wb * m) / (At * m²)

= wb/Atm

Capacity of phase advancing plant 
=P[tanϕ1-tanϕ2]
= 200[0.75 - 0.5774]
= 34.52 kVAR
