conventional current

Quick Reference

A 19th-century convention, still in use, that treats any electrical current as a flow of positive charge from a region of positive potential to one of negative potential. The real motion, however, in the case of electrons flowing through a metal conductor, is in the opposite direction, from negative to positive. In semiconductors hole conduction is in the direction of the conventional current; electron conduction is in the opposite direction.
