What type of current flows in one direction only?

• A. Alternating Current (AC)
• B. Direct Current (DC)
• C. Static Current
• D. Flowing Current

Answer: (B)

Direct Current (DC) is the type of current that flows in one direction only. In a DC circuit, the electric charge flows consistently and steadily from the positive terminal to the negative terminal without changing direction. This unidirectional flow is characteristic of sources like batteries and solar cells, which provide a constant voltage. Understanding the significance of DC is crucial because it is widely used in various applications, such as powering electronic devices, electric vehicles, and in charging batteries, where consistent and stable power is essential. This characteristic of direct flow distinguishes it from alternating current, which periodically reverses direction, as well as static and flowing currents, which are not precisely defined electrical terms in the context of current flow direction.
