What type of electrical circuit allows electrons to travel in a single loop?

• A. Series circuit
• B. Parallel circuit
• C. Open circuit
• D. Complex circuit

Answer: (A)

The correct answer identifies a series circuit, which is characterized by a single pathway through which electric current can flow. In a series circuit, all components are connected end-to-end, creating a single loop for electrons to travel. This means that the same current flows through each component in the circuit, one after the other. If one component in a series circuit fails or is removed, the entire circuit is interrupted, and the flow of electricity stops. This is a fundamental characteristic of a series configuration, emphasizing the dependency of the components on one another. In contrast, a parallel circuit consists of multiple pathways for current to flow, allowing electrons to travel through various branches simultaneously. An open circuit refers to a break in the path that stops current flow entirely, while a complex circuit generally describes configurations with both series and parallel components, rather than a straightforward single loop. Understanding these distinctions helps clarify why a series circuit is specifically defined by its single-loop structure.
