What type of electrical circuit has components arranged in a single path?

A series circuit is defined by having all its components connected in a single path, meaning that the electrical current flows through one component after another in a sequential manner. This arrangement ensures that the same current flows through each component in the circuit. If one component fails or is disconnected, it breaks the entire pathway, causing all connected devices to stop working.

In contrast, other circuit types, such as parallel circuits, have multiple paths for current to flow, allowing other components to remain operational if one component fails. A complex circuit may involve both series and parallel connections, and an open circuit refers to a break in the path that interrupts the flow of electricity, rendering the circuit non-functional. Understanding the characteristics of a series circuit is essential for troubleshooting and designing effective electrical systems.
