We can see how circuits work, and represent them with ... These could be batteries, solar panels, or a power supply connected to the mains - anything that can provide power to our circuit.

Powering electronic devices requires the testing of power supply and charging circuits, battery management systems (BMSs), and battery cells. Many of these circuits require voltage, current, and power ...

Their benefits are such that it’s become surprisingly rare to see a traditional linear power supply with a mains-frequency transformer and rectifier circuit, so [ElectroBoy]’s dual voltage PSU ...
