In a series circuit, the components are connected end-to-end, creating a single pathway for the current to flow. This means that if one component fails, the entire circuit will be interrupted.
In a parallel circuit, the components are connected in multiple branches, each with its own pathway for the current to flow. This allows the current to continue flowing even if one component fails.
Series circuits have the same current flowing through each component, while parallel circuits have the same voltage across.
