What type of circuit contains components that are arranged in a single path?

A series circuit is defined by its configuration where all components are connected in a single, continuous path. In such a circuit, the same current flows through each component, and if one component fails or is disconnected, the entire circuit is interrupted and stops functioning. This characteristic of a series circuit distinguishes it from parallel circuits, where components are connected across multiple paths and can operate independently of each other.

Additionally, terms like "complex circuit" and "combined circuit" refer to configurations that may include both series and parallel arrangements, making them inherently different from a pure series circuit. Thus, the term series circuit accurately describes a configuration where all components are reliant on each other in one uninterrupted pathway.
