In a series circuit, the components are connected end-to-end, forming a single path for the current to flow. This means that the current is the same throughout the circuit, but the voltage is divided among the components. If one component fails, the entire circuit will be broken.
In a parallel circuit, the components are connected in separate branches, each forming its own path for the current to flow. This means that the voltage is the same across all components, but the current is divided among them. If one component fails, the other branches will still have current flowing through them.
In summary, the main differences between series and parallel circuits are how the components are connected and how the current and voltage behave in each type of circuit.
