What type of circuit is characterized by a continuous path for current to flow?

A closed circuit is defined as a complete, uninterrupted path that allows electric current to flow freely through it. In such a circuit, all components—such as power sources, resistances, and conductors—are connected in a way that forms a loop. This loop enables current to travel from the power source, through the loads, and back to the source without any breaks.

In contrast, an open circuit lacks a complete path, which prevents current from flowing, thus rendering the circuit inoperable. A short circuit occurs when a low-resistance connection forms between two points in a circuit, leading to excessive current flow that can cause overheating or damage to components. A complex circuit involves numerous components and connections that may complicate the routing of current but is not inherently defined by the continuous path characteristic.

The key distinction here is the uninterrupted nature of the path in a closed circuit, which is essential for the functionality of any electrical system relying on consistent current flow.
