Alternating Current -AC vs. Direct Current-DC
The difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or "forward." In AC, electrons keep switching directions, sometimes going "forward" and then going "backward."
Alternating current is the best way to transmit electricity over large distances.
