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.

Are the standard strand of Christmas lights connected in series or parallel? What's the difference between series and parallel anyway?

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

Ellie and James explore series and parallel circuits. They also discuss the differences between current and resistance across different circuits and how to calculate them.
