GCSE; WJEC; Electric circuits – WJEC Resistors in series and parallel. Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits.

Complex circuits may have some resistors connected in series, and some connected in parallel. For example, the following combination of resistors shows two resistors connected in series, and three ...

For example, what happens when there are multiple batteries, connected in parallel? And what happens when we add capacitors into the mix, with resistors in our DC circuits?
