Question
The electric field points to the right in a wire, resulting in a current due to moving electrons.
A. the electron shift velocity points left and the current density points right
B. the electron drift velocity points right and the current density points left.
C. The electron drift velocity and the current density both point right
D. The electron drift velocity and the current density both point left
E. The electron drift velocity points left but the direction of the current density cannot be determined.
Explanation / Answer
A. the electron shift velocity points left and the current density points right
charge on electron is negative so its velocity is opposite to electric field and current is always in direction of electric field
