Direct current is described as bidirectional.

Direct current is described as bidirectional.

• A. Sometimes
• B. True
• C. Never
• D. False

Answer: (D)

The main idea is how current direction behaves. Direct current flows with a constant polarity, so the electrons move in one single direction from the source through the circuit. Bidirectional means the current reverses direction periodically, which is a hallmark of alternating current. Because DC maintains that fixed direction, describing it as bidirectional isn’t correct. In real life, batteries and DC power supplies provide steady, one-way current, while household power is AC and reverses direction regularly. That’s why the statement is false: DC is unidirectional.
