In what type of circuit are electrical devices connected in a single continuous loop?

In a series circuit, electrical devices are connected end-to-end in a single continuous loop, forming one pathway for the current to flow. This means that the same current flows through each component in the circuit. If one device fails or is removed from the circuit, it breaks the loop, and all devices connected in series will stop functioning because the flow of electricity is interrupted.

This configuration is different from a parallel circuit where devices are connected across multiple pathways, allowing the current to flow through each component independently. In a complex circuit, there may be both series and parallel arrangements, while a simple circuit typically refers to a straightforward configuration, which may not always specify the connection type.

Thus, the definition of a series circuit aligns perfectly with the question asked, confirming that this type of circuit indeed consists of components in a single continuous loop.
