Directions : In the following questions, A statement of Assertion (A)...
Assertion (A): The resistance of the superconductor is zero.
Reason (R): Superconductors are used for electrical power transmission.
The correct answer is option B: Both A and R are true but R is NOT the correct explanation of A.
Explanation:
Resistance of superconductors:
- A superconductor is a material that exhibits zero electrical resistance when cooled below a certain critical temperature.
- This means that when a current is passed through a superconductor, no energy is lost due to resistance, and the current can flow indefinitely without any loss of electrical power.
- This property of zero resistance is a key characteristic of superconductors.
Superconductors and electrical power transmission:
- Superconductors are used for electrical power transmission because of their ability to carry large amounts of current without any energy loss due to resistance.
- When electricity is transmitted over long distances, a significant amount of energy is lost as heat due to the resistance of the transmission lines.
- By using superconducting materials for power transmission, this energy loss can be greatly reduced or eliminated altogether.
- Superconducting power transmission systems have the potential to be much more efficient and cost-effective compared to traditional power transmission systems.
Relation between Assertion and Reason:
- Both the Assertion and Reason are true.
- The Assertion states that the resistance of a superconductor is zero, which is a correct statement.
- The Reason states that superconductors are used for electrical power transmission, which is also a correct statement.
- However, the Reason does not provide a correct explanation for why the resistance of superconductors is zero.
- The zero resistance property of superconductors is a result of their unique quantum mechanical behavior, specifically the formation of Cooper pairs of electrons that can move through the material without scattering off impurities or lattice vibrations.
- The Reason only highlights one application of superconductors (power transmission) but does not explain the underlying physics behind their zero resistance behavior.
Therefore, the correct answer is option B: Both A and R are true but R is NOT the correct explanation of A.
Reason (R): Superconductors are used for electrical power transmission.
The correct answer is option B: Both A and R are true but R is NOT the correct explanation of A.

Directions : In the following questions, A statement of Assertion (A)...
Resistance of the superconductor falls to zero at critical temperature. This property is very useful for power transmission without any loss. Assertion and reason both are true but reason does not explain the assertion.
