The charge carriers in a metal are typically negative. A positive charge carrier
A) will not change the sign of the Hall potential.
B) will change the sign of the Hall potential.
C) will have a zero Hall potential.
D) will produce a Hall effect across the other face of the metal.

Question

Quizplus · Accepted Answer

The Hall effect is dependent on the charge of the carriers; if the charge carriers are positive instead of negative, the direction of the Hall voltage will reverse, thus changing the sign of the Hall potential.
