Vedclass · Answer

(B) The Assertion is correct because a superconductor has zero electrical resistance at temperatures below its critical temperature. According to Ohm's law,$V = IR$. Since $R = 0$,the current $I$ can persist indefinitely without any energy loss,even when the external power source is disconnected.The Reason is also correct. The Meissner effect is a characteristic property of superconductors where they expel magnetic fields from their interior when cooled below the critical temperature $(B = 0)$.However,the Meissner effect describes the expulsion of magnetic flux,not the persistence of current due to zero resistance. Therefore,the Reason is not the correct explanation for the Assertion.

Assertion: $A$ current continues to flow in a superconducting coil even after the switch is off.
Reason: Superconducting coils show the Meissner effect.
