Question 1 of 10
1. Question
2 points
Which of these are the fundamental properties of a superconductor?
1.Zero resistance to electrical current
2.Ferromagnetism
Select the correct answer code:
Correct
Superconductivity is a state in which a material shows absolutely zero electrical resistance. While resistance is a property that restricts the flow of electricity, superconductivity allows unhindered flow.

Question 6 of 10
6. Question
2 points
Consider the following statements.
1.Energy produced using various forms of ocean energy such as tidal, wave and ocean thermal energy conversion are considered as Non-Renewable Energy.
2.Osmotic energy is the energy produced from the movement of water across a membrane between a saltwater reservoir and freshwater reservoir.
Which of the above statements is/are correct?
Correct
The government has declared ocean energy as Renewable Energy.
Accordingly, the Ministry of New and Renewable Energy has clarified that energy produced using various forms of ocean energy such as tidal, wave, ocean thermal energy conversion etc. shall be considered as Renewable Energy and shall be eligible for meeting the non-solar Renewable Purchase Obligations (RPO).

Question 9 of 10
9. Question
2 points
Consider the following pairs:
Grey hydrogen: Hydrogen not produced from fossil fuels
Blue hydrogen: Hydrogen generated from fossil fuels with carbon capture and storage options.
Green hydrogen: Hydrogen generated entirely from renewable power sources
Which of the above pairs are correctly matched?
Correct
The sources and processes by which hydrogen is derived, are categorised by colour tabs.
Hydrogen produced from fossil fuels is called grey hydrogen; this constitutes the bulk of the hydrogen produced today.
Hydrogen generated from fossil fuels with carbon capture and storage options is called blue hydrogen;
Hydrogen generated entirely from renewable power sources is called green hydrogen. In the last process, electricity generated from renewable energy is used to split water into hydrogen and oxygen.
