Understanding Current Direction

The video tutorial explains the movement of electrons in two ways: direct current (DC) and alternating current (AC). Direct current involves electrons moving continuously in one direction, as seen in batteries. Alternating current, used in homes and schools, involves electrons reversing direction regularly, changing direction 120 times per second.
