Current in a conductor is normally due to:
A)the collective motion of all electrons in the conductor
B)the thermal motion of the conduction electrons
C)the drift motion of the conduction electrons due to electric fields
D)the drift motion of both electrons and positrons
E)the drift motion of both electrons and protons

Question

Quizplus · Accepted Answer

The current in a conductor is normally due to the drift motion of the conduction electrons, which is caused by the presence of an electric field. While all of the given options involve electrons, only option C specifically mentions the drift motion caused by electric fields.
