Question

A metal wire lies along the x axis of a system of coordinates. An electric field pointing in the -i direction is applied. In what direction is the resultant conventional current?

Answer 1

The electric field direction within a circuit is by definition the direction that positive test charges are pushed. Thus, these negatively charged electrons move in the direction opposite the electric field. ... The direction of an electric current is by convention the direction in which a positive charge would move.in other hand Current is flow of charges, and charge movement is decided by field direction. Since conventional current direction is defined by direction of positive charges, and movement of positive charges is in the direction of the field, both field and current have same direction. So current direction also -i direction same as electric field applied. Thank you
