An open circuit contains what?

An open circuit contains what?

• A. Closed
• B. Ground
• C. Open
• D. Short

Answer: (C)

An open circuit contains an opening in the conducting path that prevents a complete loop. Because the loop isn’t closed, current cannot flow, so the load won’t operate. This is different from a closed circuit, where the path is complete and current can travel from the source through the load and back. A short is a low-resistance bypass that can cause excess current, and ground is a reference/return point—not the absence of a path. So, the defining idea is the gap that stops any current from flowing.
