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 ...

At this point, the decision is made as to whether and how many intermediate circuit voltages need to be created. Figure 1 shows a typical block diagram of a power supply. The 24V supply voltage of an ...

In series circuits, the current is the same through each component. The potential difference of the power supply is shared between the components. A parallel circuit showing two bulbs, a switch ...

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.
