1. Assertion (A): In Hall effect the O.C. transverse voltage developed by a current carrying semiconductor with a steady magnetic field perpendicular to the current direction has opposite signs for n and p semiconductors. Reason (R): The magnetic field pushes both holes and electrons in the same direction.
