Continuity in an electrical circuit is best described as?

• A. The circuit is open and cannot allow current to flow.
• B. The circuit is open (or incomplete) when electrons can flow from one terminal to the other.
• C. The circuit is continuous (or complete) when electrons can flow from one terminal of the power source to the other.
• D. The circuit has zero resistance.

Answer: (C)

Continuity means there is a closed, unbroken path for current to travel from the power source back to itself. When the loop is complete, electrons can flow through conductors and loads all the way from one terminal of the source to the other, so current can circulate. If any gap or break exists, the path is open and current cannot flow, which is why such a situation is described as open or incomplete. The idea that the circuit has zero resistance is not what continuity defines; a continuous path can have some resistance and still carry current. Similarly, an open circuit describes a broken path where current cannot flow, not continuity.
