What kind of electrical circuit allows current to flow in multiple paths?

A parallel circuit allows current to flow in multiple paths. In this type of circuit, each component is connected across the same two points, providing separate paths for current. Because of this configuration, if one path is interrupted or has a failure, the other paths remain unaffected, allowing for continued operation of the other components. This design is particularly useful in applications where reliability is critical, such as in HVAC systems, as it ensures that the failure of one part does not stop the entire system from working.

In contrast, a series circuit has components connected end to end in a single path, meaning that the failure of one component causes the entire circuit to cease functioning. A closed circuit refers to a complete path for current but does not specify the arrangement of components, so it does not imply multiple pathways. A complex circuit may contain both series and parallel configurations but does not explicitly indicate multiple paths for current. Therefore, the characteristic of allowing current to flow in multiple paths is unique to parallel circuits.
