Which description best defines a series circuit?

In a series circuit, all components are connected end-to-end in one continuous loop, giving a single path for the current. Because there’s only one path, the same current flows through every component, so the description “all components joined in one loop” fits best. The idea where current splits between branches describes a parallel arrangement, not series. A statement about components in parallel loops also points to parallel wiring. Saying there’s just a single resistor is too restrictive—series circuits can include multiple components lined up in that one loop. In short, a series circuit is all components in one loop with the same current through each part.
