Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

The current flowing in a series circuit is the same everywhere. Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits ...

Two lamps connected in series with ... same throughout a circuit and voltages add up to the supply voltage. Components that are connected on separate loops are connected in parallel.
