What type of electrical current flows in only one direction?

The type of electrical current that flows in only one direction is Direct Current (DC). This means that the electric charge moves consistently in a single direction, which is typical in batteries and many electronic devices. In contrast to Alternating Current (AC), where the charge reverses direction periodically, DC has a constant polarity and voltage. This characteristic makes DC ideal for applications that require a stable and predictable power source, such as in portable electronics and many circuits.
