Series Circuit - GCSE Physics Definition

A series circuit is a type of electrical circuit in which all the components are connected one after another in a single pathway, so there is only one path for the electric current to flow. In a series circuit, the same current flows through each component, like lights or resistors, but the voltage is shared between them. If any part of the circuit is disconnected or if a component fails, the entire circuit will stop working because the electric path is broken. Series circuits are simple, but they have limitations because the more components you add, the dimmer things like bulbs can become, as the voltage is divided.
