There are two basic ways in which to connect more than two circuit components: in series or in parallel.
The basic idea of a “series” connection is that components are connected end-to-end in a line to form a single path through which current can flow.
The basic idea of a “parallel” connection, on the other hand, is that all components are connected across each other’s leads. In a purely parallel circuit, there are never more than two sets of electrically common points, no matter how many components are connected. There are many paths for current flow, but only one voltage across all components.
