Question

Assertion A: Superconductivity arises from electrons forming Cooper pairs due to electron phonon interaction Reason R: Cooper pairs have lower energy and move without scattering leading to zero resistance In the light of the above statements, choose the most appropriate answer from the options given below
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

In superconductors:
• Electrons form Cooper pairs
• Cooper pairs move without scattering
• Resistance becomes zero

Answer 1

The Correct Option is A
