Two lamps connected in series with an open switch ... Two lamps connected in parallel with an open switch and a cell The circuit diagram shows a circuit with two lamps connected in parallel.

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.

In series circuits, the current is the same through each component. The potential difference of the power supply is shared between the components. A parallel circuit showing two bulbs, a switch ...
