Statement A states that an electric or mechanical input makes the flux jump from one superconductor to another, generating large direct current. This statement is not accurate. Superconductors are materials that exhibit zero electrical resistance below a certain critical temperature. They allow for the flow of electrical current without any significant loss of energy due to resistance. However, the generation of large direct current by making flux jump between superconductors is not a common or typical phenomenon associated with superconductivity.
Statement R states that the electric resistivity of superconductors depends upon the magnetic field. This statement is true. Superconductors are known for their ability to expel magnetic fields from their interior, a phenomenon known as the Meissner effect. When a superconductor is subjected to a magnetic field, it generates a screening current that exactly cancels out the magnetic field within the material, resulting in the expulsion of the magnetic field. This behavior is one of the defining characteristics of superconductors.
Therefore, statement A is incorrect as it does not accurately describe the behavior of superconductors. However, statement R is true as the electric resistivity of superconductors does depend on the magnetic field, as explained by the Meissner effect.
Hence, the correct answer is d. R is false but R is true.
