DC stands for **Direct Current**. It refers to the flow of electric charge in a single direction, which means the current flows steadily from the negative side to the positive side of a power source, like a battery.
In simpler terms, DC current is a type of electric current where the electrons move in one constant direction, unlike AC (Alternating Current), where the direction of current changes back and forth.
An example of DC current would be the power used in a flashlight or a phone battery.
