What type of circuit allows components to share the same current path?

A series circuit is designed so that all components are connected end-to-end in a single path for current to flow. In this configuration, the same amount of current flows through each component sequentially. If any component fails or is removed, the entire circuit is interrupted, and current cannot flow. This characteristic is crucial for understanding how series circuits work, as the shared current path contributes to the behavior and calculations of voltage, resistance, and overall circuit performance.

In contrast, while node circuits and complex circuits may contain elements of series or parallel configurations, they are not defined by a single current path shared by all components as in a series circuit. Parallel circuits, while allowing multiple paths for current to flow, do not share the same single current path—each branch has its own path for current to travel through, which distinguishes them from series circuits.
