Question : Read the passage and answer the following questions.
IIT Delhi researchers have designed and fabricated a device that can generate electricity from water drops, raindrops, water streams, and even from ocean waves using "Triboelectric Effect" and "Electrostatic Induction". The device is called "Liquid-solid Interface Triboelectric Nanogenerator". The generated electricity can be stored in batteries for further use. Triboelectric effect is a known phenomenon for a long time, and in this effect, charges are generated when two surfaces are in friction. The best example we see are sparkling lights when we move the blankets/jackets.

The device has a very simple structure consisting of specially designed nanocomposite polymers and contact electrodes and can generate a few Milliwatt mW power, which is sufficient to power small electronic devices like watches, digital thermometers, radio frequency transmitters, healthcare sensors, pedometers. When compared to conventional methods, such as the use of the piezoelectric effect, the present device can generate significantly more electricity.

The researchers successfully incorporated nanostructures into a polymer matrix, which enhanced the film's surface roughness, polarizability, and hydrophobicity, among other characteristics, as a result. Due to the enhancement in the above property, the flexible film is used to fabricate the device where raindrops have just to slide down and can generate electricity. The artificially created rough surface allows to generate more charge and superhydrophobic properties of the solid surface help to roll the water drop without getting stick to the surface.

The IIT Delhi research team also explored the underlying mechanism of the electricity generated when the water drop comes in contact with the solid surface and it is shown that saline water drops generate more electricity. The researchers also showed that the device can even work with ocean waves, where the water is saline, and through the ocean waves contacting the surface of nanocomposite polymer film, electricity is generated.

Question:Name the electronic devices which can be powered with the device mentioned in the passage:
1. Watches
2. Pedometers
3. Refrigerators
4. Radio Frequency Transmitters

 

Option 1: Only 1 and 2
 

Option 2: All 1,2,3, and 4
 

Option 3: Only 3 and 4
 

Option 4: Only 1,2 , and 4

Correct Answer: Only 1,2 , and 4


Solution : The correcrt option is 4 i.e  "Only 1, 2, and 4."
Explanation:

 Let's refer to the following lines of the passage:

The device has a very simple structure consisting of specially designed nanocomposite polymers and contact electrodes and can generate a few Milliwatt (Mw) power, which is sufficient to power small electronic devices like watches, digital thermometers, radio frequency transmitters, healthcare sensors, pedometers. 
The above statement clearly mention the watches, pedometers and radio frequency transmitters.

Correct Answer: Indian Statistical Institute, Calcutta


Solution : The correct option is Indian Statistical Institute, Calcutta.

The "Hole Card System," India's first computer, was established at the Indian Statistical Institute (ISI) in Calcutta (now Kolkata). This computer, which was built in-house at ISI, went into operation in 1955. The Hole Card System was a key milestone in the history of computers in India, and it was employed at the Indian Statistical Institute for different statistical and scientific objectives.

Hello,


IITs are known for their excellent package and their top notch facilities and education.

The highest package for IIT Delhi Placements 2023 was INR 2.5 Crores and the average package was INR 18-20 LPA. The overall percentage for IIT Delhi Placement was 84.94%

However, the other students who do not get placed are either preparing for further education or have got internships.


I hope this helps,

Thank you

Hello Aspirant,

The jee mains / advanced eligibility criteria are as follows -

  • Candidates should pass from any recognised board or University in their class 12th.
  • Candidates should opt for physics chemistry and mathematics as mandatory subjects in their class 12th.
  • Candidates should secure a minimum of 75 percentage in their class 12th.

There are many courses offered by IIT Delhi

Hello Aspirant,

For IIT Delhi you have score very good marks in jee advanced to get into this college. The total  marks are not fixed in jee advanced so I consider total marks of 360 you need to score atleast 160+ marks to get a branch in IIT Delhi.

For computer science you need to be under 200-300 rank all India and for lower branches upto 2000 rank you can get branches like civil, metallurgy and integrated courses.
