If there are no branches then it's a series circuit. If there are branches it's a parallel circuit. In a television series, you get several episodes, one after the other. A series circuit is similar.

A parallel circuit is way of connecting components on separate branches, so the current can take different routes around the circuit. The current is different in different parts of a parallel circuit.

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.
