What type of circuit features components connected end-to-end?

A series circuit is characterized by components connected end-to-end, which means that the current flows through each component in a single path. This arrangement implies that the same current passes through all components in the circuit. If one component fails or is removed, the entire circuit path is interrupted, causing all components to stop functioning.

In contrast, a parallel circuit features components that are connected across the same voltage source, allowing current to flow through multiple pathways. A combination circuit includes elements of both series and parallel configurations. A closed circuit simply refers to a complete circuit with no breaks, but it does not specify the arrangement of the components. Thus, the defining feature of a series circuit is the sequential connection of its components, which directly leads to the understanding that the answer is indeed a series circuit.
