Q. Identify the incorrect statement regarding a superconducting wire
A) Transport current flows through its surface
B) Transport current flows through the entire area of cross-section of the wire
C) It exhibits zero electrical resistivity and expels applied magnetic field
D) It is used to produce large magnetic field
Explanation
(b) In superconductors, the current flows on the surface so that it exactly cancels the magnetic field inside the metal. Therefore statement (b) is not correct
