Q112 / 120 · VITEEE 2008 · Physics

Identify the INCORRECT statement regarding a superconducting wire

  • A
    transport current flows through its surface
  • Correct answer
    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

Solution

The transport current flows through the surface of the superconducting wire and not through the entire area of cross-section of the wire.

Hence, the correct answer is option: 'B'.
