What type of circuit configuration connects components end to end?

The correct answer is a series circuit because in this configuration, components are connected end to end, creating a single pathway for electrical current to flow. When components are arranged in series, the current that flows through each component is the same, and the total resistance in the circuit is the sum of the individual resistances of each component.

This arrangement means that if one component fails or is disconnected, the entire circuit will be interrupted, stopping the flow of current. This characteristic of series circuits is essential for understanding how various components, such as resistors, batteries, and light bulbs, interact in an electrical system.

In contrast, a parallel circuit connects components alongside each other, allowing multiple pathways for current to flow. A mixed circuit incorporates both series and parallel connections, while a closed circuit simply refers to a complete electrical loop, but does not specify the configuration of the components. Each of these alternatives shows different electrical properties and behaviors compared to a series circuit.
