Alternating Current (AC) vs. Direct Current (DC)learn

In direct current (DC) the electric charge (current) only flows in one direction. Electric charge in alternating current (AC) on the other hand changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction. Most of the digital electronics that you build will use DC.
