What type of electrical current flows in only one direction?

Explanation:
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.
