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.

The current flowing in a parallel circuit can be investigated by connecting the circuit below. Once more, put one ammeter in position A 1 and record the reading in a suitable table. The current in ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
