We have current when the charge carriers have a net drift velocity Vd superposed on any random motion. By convention, the current density has the same direction as the drift velocity of positive charge carriers (and the opposite direction as the vd of the negative charge carriers). Which of the following statement is true about the flow of the negative charge carriers

Expert Solution
Step 1
The correct answer is option 2.
The current density is the flow of current from the unit area of the wire. Its direction is same as flow of current and flow of current is flow of positive current. So drift velocity of negative charge carrier is opposite to the current density.
