All of these are big differences

Detailed explanation-1: -Electric current flows in two ways as an alternating current (AC) or direct current (DC). The main difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, while electrons keep switching directions, going forward and then backwards in AC.
Detailed explanation-2: -With dc, you’ve got a steady current in one direction, whereas with ac, both the magnitude and direction of the current change.
Detailed explanation-3: -Alternating current (AC) is an electric current that periodically reverses its direction, in contrast to direct current (DC) which only flows in a single direction which cannot change sporadically.
Detailed explanation-4: -direct current, abbreviation DC, flow of electric charge that does not change direction.
