In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and produces a lower voltage. The first one won’t ...

This type of linear power supply has an extremely simple circuit consisting of a transformer, bridge rectifier, and capacitors. The transformer isolates and steps down the AC voltage, the ...

Adding more batteries to a simple circuit will increase the electrical energy, which will make a bulb brighter. Electricity can flow through the components in a complete electrical circuit.

Because, unlike a simple string of lights in a series circuit, these are all arranged in a parallel circuit. And you can think of a parallel circuit as having several different routes that all run ...
