Series and parallel circuits

Electrical circuit components can be connected together in one of two ways: series or parallel. These two names describe the method of attaching the components, that is one after the other or next to each other. If two or more circuit components are connected end to end like a daisy chain, it is said they are connected in series. A series circuit is a single path for current through all of its components. If two or more circuit components are connected like the rungs of a ladder it is said they are connected in parallel. A parallel circuit is a different path for current through each of its components. A parallel circuit provides the same voltage across all its components.
