An Open Circuit is best described as which of the following?

• A. Incomplete circuit; there is a gap. Electricity cannot flow.
• B. Open Circuit
• C. Complete circuit; no gaps. Electricity can flow.
• D. Circuit with multiple paths; electricity can still flow if one path gets obstructed.

Answer: (A)

An open circuit is all about an incomplete path for current. When there’s a break in the conducting loop—like a switch left open or a broken wire—the circuit isn’t closed, so electrons have nowhere to go and the current cannot flow. That’s why electricity doesn’t move in an open circuit. In contrast, a complete circuit has a closed loop and allows current to flow, and a circuit with multiple paths can still carry current if at least one path remains conductive.
