Two common types of circuits are series and parallel. An electric circuit consists of a collection of wires connected with electric components in such an arrangement that allows the flow of current within them. A series circuit has no branches but instead has several components arranged one after the other.
In a series circuit, the electric current flows through the first component, then through the second, and finally to the subsequent ones until it reaches the battery again. It aligns bulbs in a way that creates a single pathway for the charge flow. Unlike the series circuit, components in a parallel circuit have branches instead of end-to-end components. Other types of circuits include series-parallel and complex circuits.
