Which term describes current that flows in a single direction?

• A. Alternating Current (AC)
• B. Direct Current (DC)
• C. Solenoid
• D. Generator

Answer: (B)

Direct current describes current that flows in a single direction. In DC, the charges move steadily in one way through a circuit, unlike alternating current, which periodically reverses direction and keeps changing the path of flow. A solenoid is just a coil of wire used to generate magnetic fields when current runs through it, not a description of how the current itself moves. A generator is a device that produces electrical energy and can deliver either AC or DC depending on its design; what matters here is that the term for current moving in one direction is DC.
