What is the difference between AC and DC current?

AC current stands for alternating current, while DC current stands for direct current. The main difference between the two is the direction in which the electric charge flows. In AC current, the electric charge changes direction periodically, while in DC current, the electric charge flows in one direction constantly.

AC current is commonly used in households and buildings for powering electrical appliances, thanks to its ability to easily be transformed and transmitted over long distances. On the other hand, DC current is often used in devices that require a constant and steady flow of electricity, such as batteries and electronic circuits.
