A current that flows in one direction is called which type of current?

• A. Sporadic current
• B. Alternating current
• C. Direct current
• D. All of the above

Answer: (C)

Direct current is current that flows in one direction. In a DC circuit, electrons move steadily toward the same endpoint, giving a constant direction and polarity. This is why batteries and many small electronic power supplies produce direct current. Alternating current reverses direction periodically, so the flow changes back and forth. Sporadic current isn’t a standard category for power flow, so it doesn’t represent a consistent one-direction flow. Therefore, the description fits direct current best, not alternating or an undefined category, and not all of the above.
